In order to make the Sandbox easier to use, a new Sandbox question will be posted when the old one becomes too full. This Sandbox is currently active. You can check here for the full list of past and present Question Sandboxes.

What is the Sandbox?

This "Sandbox" is a place where Worldbuilding.SE users can get feedback on prospective questions they wish to post. This is useful because writing a clear and fully specified question on the first try can be difficult. There is a much better chance of your question being well received if you post it in the Sandbox first.

To post a question to the Sandbox: Post an answer to this post with the content of your proposed question. You can create as many answers as you have proposed questions, but it is recommended that you only work on one question at a time. The content of the post should be as close as possible to the format you would use when asking on the main site. If you would like, you may add a section at the bottom explaining what parts of the proposed question you are most worried about (See the Sandbox FAQ for more information on suggested syntax).

Once you have posted your proposed question, users will be able to comment on it with feedback. You can then respond to their feedback with comments of your own, or make edits to your post to attempt to address their feedback (after editing, be sure to comment to notify the user that you have taken their advice). The feedback/edit cycle can go on for as long as needed until either you are confident that your question is ready to be asked on the main site, or you've decided the question just won't work.

When you think your question is ready for the public, go ahead and post it to the main site. To help keep this sandbox clean, you should edit your post here so that it contains the title and URL of the posted question, and nothing else. Regardless of whether or not you decided to post to the main site, once you are done with your Sandbox post, you should delete it. This will not completely delete the post, but it will get it out of the way so that new proposed questions can be more easily located.

Keep the Sandbox clean. In order to keep the Sandbox clean users are encouraged to look out for questions that have not seen any activity in some time. If you come across a question draft that has not seen any activity from the author in the form of edits to the draft and comments as responses to other peoples comments you should leave a comment. In the comment you should ask if the user is still working on the question draft and remind him that his post might be deleted in the future if there is no further activity. If you see a question draft that has not seen any activity for at least 30 days and that has had a comment asking if the author is still working on the question draft for at least a week you should flag the post for moderator attention and ask for deletion. This helps to keep the Sandbox clean in cases where the author has abandoned his question draft.

Delete your comments when they no longer apply. It's normal that the OP will incorporate the feedback they get into their posts. Please make it easy for others to see which comments are still relevant to the discussion by removing your obsolete ones. In addition you can ask a mod to purge comments under graduated posts or move them to chat under abandoned posts to make it easier for users that can see deleted posts to use the Sandbox.

Use votes sparingly. Up- and Downvotes in the Sandbox should be used sparingly as the drafts here are supposed to be questions that would not fit the guidelines of the Main site in their current form. Only upvote if you think a draft is ready for the Main site and only downvote if you think that a question is just not a good fit, no matter how much the OP works on the draft. In any case, please write a comment to explain your voting. We don't want to unnecessarily discourage the OP, but we also don't want them to waste their time.

Please avoid answering questions here. I know it's tempting, but answering the question in a comment will clog the comments and make it harder to see good guidance. If you have an answer for the proposed question, simply wait for it to be posted to the main site, and answer it there.

See the Sandbox FAQ for more information on how to use the Sandbox.

Please make sure you wait at least a day after posting into the Sandbox to give a range of people time to see the question and respond.

The Sandbox works best if you sort posts by "active" (click here to do so).

how can a planet's radiation cause sterility in the population, but not be fatal

My setting takes place on a planet that has high level of radiation due to a factor unknown to the population. This factor is not man-made, but due to some change in the planet's environment. As a result, a large percentage of people over have become sterile. The range is as high as 50-70%. This severely hurts population growth. However, the radiation doesn't affect people in any other way, and infertile people don't suffer any other effects from it, such as cancer, pain, etc.

How could these parameters come to be? What factors would need to be met on a planet for this to happen realistically?

  • $\begingroup$ Hi Incognito, I think this is a good question and pretty much ready for Main. One recommendation - I have a little background in biology, and I'm not sure it's possible to do what you're interested in, so I might rephrase to ask "is this possible" and reality-check that. Once you've established that it's possible for radiation poisoning to cause sterility without fatality, I'd ask a followup asking how those conditions could arise on a natural planet. Otherwise, I suspect you'll largely get frame-challenges that tell you it's impossible. $\endgroup$ – Dubukay Dec 12 '18 at 20:38

how could creating a familiar permanently bind you to a certain type of magic?

Orgone is the measure of a person's connection with the cosmos. It is the conduit through which the power of the cosmos flows, focused through a sorcerer's will. Ritual practicioners must draw on this reserve of power to make a magic spell work. Spells require a constant infusion of Orgone through rituals that are performed inside a transmutation circle. These rituals require a number of ingredients and can last anywhere from 30 minutes to several hours depending on the spell. There are five types of magic that spells revolve around.

Enchantment Spells – These are spells designed to capture cosmic power within a crafted item, so that its power can be called upon in times of need.

Scrying Spells – These are spells designed to allow a user to perceive in ways that go beyond his fve senses.

Protection Spells – These are spells designed to ward a user, object, or location against a variety of possible harms

Transmogrifcation Spells – These are spells designed to fundamentally alter or control another being

Transmutation Spells - Changing the makeup of different materials or combining them with others to make new forms of matter.

A mage can create a familiar, creatures made purely from orgone, to assist in their rituals. They are made from a mage's souls and serve as a direct reflection of their inner self. They may have unique abilities, but their main purpose is to serve as magical batteries. They allow a mage the ability to bypass ritual circles and their ingredients to perform spells, reducing time frame from hours to literally minutes. They also make the particular spell more powerful, allowing mages to become masters of their craft. The drawback is that it limits a mage to one of the five types of spells. While these specialist mages are the most powerful individuals in their field, once they choose which form of magic to master, they lose the ability to perform the other types forever.

I need a good reason for why a familiar binds their mage to a particular type of magic. Why would it make you all powerful in one but block your access to others?

  • $\begingroup$ I think this one is fine too, and is interesting to me! As with all magic questions, it flirts with POB but you've done a reasonable job of outlining the rules and powers of your magic. Kinda reminds me of the One Ring from Tolkien's work. $\endgroup$ – Dubukay Jan 16 at 22:03

How can the church prevent the spread of mass media across Europe during the medieval period?

How can the church stop the Mass media from spreading throughout medieval Europe?

The Protestant Reformation in the 15th century was devastating for the catholic church because it broke its exclusive hold over Christendom and ended up leading to the diverse branches of today. Due to the overspending on monuments, selling of indulgences, and the promoting of family members to valuable offices, the church made itself vulnerable to criticisms. Martin Luther and his 95 theses, referred to as the Disposition on the Power of Indulgences, brought these actions to light and eventually led to the schism that changed Europe. The Renaissance Popes saw this as a challenge to their authority. At any other time, Luther would have just been labeled a heretic and executed. However, one thing allowed him to become immortalized in the minds of the public: Johaness Gutenberg and The printing press.

The press introduced the era of mass media and communication which changed the power structure of Europe. It broke the hold that the aristocracy had over literacy, allowing the poorer dregs of society access to education and creating the middle class.The relatively unrestricted circulation of information and (revolutionary) ideas transcended borders, captured the masses in the Reformation and threatened the power of political and religious authorities. The invention of the printing press removed control of written material from the Catholic Church and made it difficult for the church to inhibit the spread of what it regarded as heretical ideas.

I, Phillip J Fry, have traveled back in time to the 14th century to save my future by warning the Pope and altering the timeline. Eliminating Guttenberg would not stop the reformation, as someone else will simply come along to invent the printing press sooner or later. For the corrupt church to continue its decadence in peace, the influence of the printing press must be curtailed. What measures should the catholic church take to stop or at least delay this from happening?

  • $\begingroup$ "because it broke its exclusive hold over Christendom" the Orthodox church in the east was also a thing. Moreover, there are other eastern early/proto Christian churches are are outside the Catholic/Orthodox split like Nestorians. Other splinters like Bogomils or Cathars also existed but were declared heresies and persecuted, rather than somewhat grudgingly accepting them by trying to ignore them like Nestorians. Yes, perhaps the Catholic church was the largest but by no means was the only church - splinters always existed. $\endgroup$ – vlaz Jan 16 at 8:30
  • $\begingroup$ I can't see many problems with this, honestly. It's on the edge of story-based because you're asking about the actions of a character or narrative, but I personally wouldn't close it. You might want to go through and do a quick grammar/consistency check (capitalizing Catholic, spelling of Gutenberg, etc.) before posting it though. $\endgroup$ – Dubukay Jan 16 at 22:00

In this premise, a culture has developed where inheritance flows through the female line. There is a Queen Mother, matriarch of the ruling family, who inherited her title from her mother. Her eldest son will be King, and her daughters will be princesses. When the King dies, the candidates for succession will be his sister's sons. An assembly made up of elected noblewomen would choose the successor to the throne. So the crown passes from uncle to nephew, maintaining the female lineage.

This world's religion worships a mother goddess. All things originally come from her, therefore all authority passes down through the female line, such as inheritance, titles, etc. However, there was a period in history in which a large number of the population were rendered sterile due to a plague. As a man can father many children at a time, culture evolved to introduce polygamy into society. The plague eventually ran its course, but the tradition continued. the King will have many wives (daughters of noble families), but none of his sons stand to inherit his position. In such a society, the uncle-nephew relationship supersedes the father-son relationship.

I would like to keep the rule of succession from king to nephew stable, but have encountered some issues with this. For starts, it is likely that a king would prefer his own son over his nephew, and will probably elect them to high positions in the government. When the king dies, the son could easily just take power from the true heir by force. Also, it is likely there will be at least some degree of rivalry between the different fathers of a sister's children, given their social status. Such issues can breed instability or civil war.

How can I introduce stability into this system and ensure that lines of succession remain sustainable?

  • $\begingroup$ "The rule of succession from king to nephew": you must actually spell out the rule. What nephew? The firstborn son of the eldest sister, the firstborn son among all the sisters, the favorite nephew selected by the king, any of the newphews selected by the assembly of noblewomen? Please also consider a comparison with systems other than the boring western European rule of primogeniture; for example, the agnatic seniority (complicated by izgoi) system of the Rurikids of old Russia, etc. $\endgroup$ – AlexP Dec 1 '18 at 21:03
  • $\begingroup$ Also, you may want to explain what you mean by "stable"; for example, despite their messy rules for succession, the Rurikids ruled Russia for seven and a half centuries, from Rurik the Varangian to Vasili IV. Do you want to avoid civil war? Do you want to avoid periods of uncertainty? Why do you believe that the specific rules of succession are more important than the rule of law in general? $\endgroup$ – AlexP Dec 1 '18 at 21:12

You may not necessarily be happy with the answers, because, as I see it, you are seeking a solution to the wrong problem. $\endgroup$ – AlexP Dec 2 '18 at 19:34

Omegaverse Society

For some reason (probably sheer variety of 'verses) I can't find any in depth analysis of this online so I'm posting this here.

Due to the many omegaverses out there, for my purposes assume the following

  • Every individual has a primary sex (male/female) and a secondary sex (alpha/beta/omega)
  • Omegas have a heat cycle, when in heat they release pheromones (Suppressants exist)
  • Alphas are especially attracted to omega pheromones
  • Betas are immune
  • All sexes can get pregnant, although omegas are more likely
  • All sexes are equally likely regardless of the parents
  • The usual characteristics of the primary sexes are retained
  • I'm not using Soulmates
  • I'm not having any intellectual/physical differences between alphas, betas and omegas other than the above


How would their society develop in the modern age given the above? I'm not really concerned about the numerous biological inconsistencies, the only thing that I'm interested in is their class system. The most important thing I need to know is how alpha/beta and beta/omega pairings might be viewed but other details are welcome

Sandbox Questions

Is this too much/too little information to base an answer on? I make a lot of bullets detailing the setting I'm in. Also, is this too broad a question (kinda falls under the too little info question)

  • $\begingroup$ Hi Blake, welcome to Worldbuilding and welcome to the Sandbox! This is an interesting question, but we're missing some information and it's currently a bit opinion-based. I don't think most users will know what an omegaverse is - I certainly didn't until after some extensive Googling. A quick introduction to what your omegaverse is, what it looks like, and how it differs from ours will be vital for giving you useful feedback on the question. $\endgroup$ – Dubukay Dec 12 '18 at 20:12
  • $\begingroup$ I do think it's currently too-broad; questions about "society" almost always are. If there's a specific question, such as "how can I keep my omegas from being enslaved", that's closer to what Worldbuilding can help you answer. Asking how something would be "viewed" is also usually opinion-based or story-based; that's a decision that you as the author should make and the onus is on you to justify why your characters feel that way. $\endgroup$ – Dubukay Dec 12 '18 at 20:13
  • $\begingroup$ I would suggest that rather than look how society develops (which is always too broad) you ask for a similar culture which you can than study and pull ideas from or Base it off sexual orientations (maybe?). Society is not uniform and differs across the globe with too many nuances that could be expressed properly. For example, in the modern world, we have, America, Japan, China and Saudi Arabia. Different societies in the modern world that are widely different. $\endgroup$ – Shadowzee Dec 13 '18 at 5:57

World-splitting Wall: Impact on Weather


The question

I asked recently in this question how paranoid aliens afraid of going the way described in "War of the Worlds" would sequester native flora and fauna in a preserve.

One of the coolest answers I saw was for the establishment of a wall, around my nature preserve, to preserve most native wildlife in its natural form. What climate anomalies could occur on the edges of the dome?


  • The moon itself is slightly larger than Mars, and orbits a Neptune-sized planet. It takes about 50 days to complete a roughly circular orbit.
  • The moon's planet orbits at 0.63 AU, making for a 230-day orbital period
  • The wall splits the moon directly in half, and is 10-15 miles tall
  • The wall is covered/painted with a dirt-like material, and has psychological deterrents to any would-be wall-crossers.

  • $\begingroup$ Have added edits. $\endgroup$ – JavaScriptCoder Dec 14 '18 at 15:21
  • $\begingroup$ Hi JavaScriptCoder, good edit! It's much clearer and more answerable. The biggest things I think we'll need to know are 1) whether the moon has an Earth-like environment or whether we're deriving climate effects from basic physics and 2) how large the moon is $\endgroup$ – Dubukay Jan 10 at 20:23
  • $\begingroup$ Some comments as far as clarity goes: you only mention a "moon" in the notes on the question - I'd introduce that information earlier and provide some additional info about the world. Also, you say in one place that the wall goes all the way up to space, and in another that it's 10 miles tall. Finally, you've still got some references to a "dome" in there - maybe take those out or replace "dome" with "wall"? $\endgroup$ – Dubukay Jan 10 at 20:25
  • $\begingroup$ Also, random thing I thought of while ruminating on this - does the wall split the world north/south or east/west or some other way? That'll change the answers a lot, with an equatorial wall having the least impact and a meridianal (meridinal?) wall having a much larger one. $\endgroup$ – Dubukay Jan 16 at 22:05

Non-Euclidean geometry where objects appear bigger the farther they are



In our ordinary flat geometry, the apparent size of objects grows proportionally to the inverse of their distance from us. However, in curved space this relationship may sometimes be modified by phenomena such as gravitational lensing.

I want to take this to the extreme and ask whether it is possible to have a non-Euclidean geometry with completely inverted perspective, where objects appear to grow with the distance instead of shrinking.

Specifically, the geometry should fulfill both of these requirements:

  • There must be at least one point for which the apparent size of all objects over a certain range of distances is proportional to their distance to this point, or very approximately so (this range should be as big as possible taking into account the second requirement). If that is not possible, I would also accept an affine behavior like $l(r) \simeq a + br$ with $b>0$, where $l$ denotes any characteristic length of an object and $r$ is distance.

  • The curvature at all points must be non-hazardous to an adult human, and the place should be easy to access from the outside.

My question is

Does such a geometry exist? If so, what would be the biggest reasonable range of distances where the phenomenon of inverted perspective holds?


This is for a short story I'm writing that is set in the future, where the protagonist wants to take her partner to a resort to celebrate their honeymoon. In this resort, gravitational engineers have built (by unspecified means) a famous scenic viewpoint in which tourists can enjoy a unique view of the surrounding landscape with inverted perspective. The lookout is situated in a tower accessed through an underground tunnel, so as not to spoil the surprise.

Is a hard coral-planet feasible?

Inspired by this answer and the mention of a hyperbolic plane, I've been imagining a world based on that geometry. The closest real-world example of such a geometry I can come up with is coral. I've been imagining a planet which is a coral, something which essentially looks like this, only much more complex, with more folds. However, I know there are going to be some problems with a world of this design.

A planet based on coral (assume we're talking about hard coral, and not soft coral) instead of solid rock might not be very structurally sound, and if the world follows the design and has sheer valleys going almost all the way to the core of the planet, that's sure to create some problems. These problems might be mitigated (or at least lessened) by making the world small, but I don't know if having a small world will help or not.

I would like to know if such a world is even remotely possible. If it is, but only with some substantial changes, that's fine with me, as long as the hyperbolic geometry is still there (if changes are required, then I'll deal with those in separate questions). So that is my question: is a hyperbolic geometric hard-coral-based world remotely possible?

Note: I'm not talking about hyperbolic space here, just the geometry of the coral. This would be a coral (anywhere from the size of a small moon to an enormous planet - depending on if size effects feasibility), native to space (not aquatic).

It is my concern that this will be marked as too broad. My dilemma is that I don't really know where to start to make such a world possible, or even if such a world is possible, so I need to know that first. How could I ask this so that it isn't too broad? Or is it fine?


  • $\begingroup$ You know a coral in a living animal? $\endgroup$ – Vincent 13 hours ago
  • $\begingroup$ @Vincent Yes. People have talked about space-trees though before, and that seems crazier than this. With a coral, you have a solid skeletal structure (which can presumably be made airtight), and add in oxygen (or whatever you need to breathe)-producing bacteria, and hydrogen to form water, and you're on your way. I should specify that I'm talking about hard corals, the ones with hard skeletons; not soft corals. $\endgroup$ – Thomas Myron 11 hours ago
  • $\begingroup$ Hi Thomas, cool question! A couple clarifications that would help me: If you’re able to, I think some numbers might help with the too-broad aspect. How big of a planet you’re hoping to have (mass, radius?) will probably change answers dramatically. Also, I’m having trouble understanding if this coral is still in hyperbolic space, or if the coral is in normal space and the folds are the “hyperbolic” part. Corals normally grow in water - are you hoping to have a water planet (or previously water planet?) that the coral grew in, or will we need to rely on novel space-coral biology? $\endgroup$ – Dubukay 8 hours ago
  • $\begingroup$ @Dubukay Good catches; I've made some edits. Let me know if they're clear: I'm trying to say that I don't know how the size of the world will effect it. If I can only have a small moon-sized coral, but anything bigger is just impossible, then I want to know that. I don't want to limit the answers by locking myself into a planet-sized coral. Does that make sense? $\endgroup$ – Thomas Myron 7 hours ago

What would be the biggest risks that a celestial oligarchy would want to eliminate?

On XX February 2XXX, 100,000 online players for a VRMMO were transported to a new world that seems to run off of the same rules as the VRMMO they played, but without the menus and status screens. Not only were they transported to this world, but their avatars were transported to this world as separate entities (henceforth: PCs) from the players themselves, but with all of the player's memories as well, but with the personality they played as. The effective levels of the players transported to this world is 0, with limited exceptions. Players transmigrate with the knowledge they had in their own world and a few items they had on them during the process. The levels of the PCs range from 1 to 100, depending on how much time was put into the game with that character. PCs also transmigrate with all the items they had in their inventory, and in rare cases their entire guild hall would be transported (a la Ainz Ooal Gown). The effective highest level people native to this world (henceforth: NPCs) is 39 in EXTREMELY rare circumstances, but NPCs are almost entirely level 15 and lower, with children being effectively Level 0.

Except for the Celestial race that is responsible for maintaining balance.

Celestials like angels are responsible for making sure mortals don't get to be too-powerful. At the same time, when these players and PCs transmigrated into the world, this shift in power would lead them to hunt down and kill anything they would deem to be a threat not just to the balance of the world, but their seat of power. Players have no mana unlike all other life in this world, so only PCs would be detected when they entered the world, but the Celestials would know of the players once they start hunting risks and encounter any players who have partnered with their PCs. (Consider it an innate "Sense Magic" skill.) Celestials range from between Level 1 to Level 75, but while one max-Level Celestial would be unable to defeat a Level 100 player, a sufficiently sized suicide-squad would, given the right circumstances and equipment.

That's it for the background information related to my specific situation, now here's the question-proper:

If a bunch of new people spontaneously appeared in a medieval-themed knights-and-magic world where a celestial oligarchy "maintains the natural balance" by any means necessary, what risks brought about by this "import" would said oligarchy want to eliminate with extreme prejudice?

Thinking on this, I came up with my own answer, but am unsure if there is anything I am forgetting or outright wrong on.

  • "Foreign" Celestials (namely angels and nephilim)
  • PCs over Level 20
  • PCs who demonstrate ownership of Summoning Items or have access to "Foreign" Guild Halls

Would this be all or would there be other risks that they'd deem need to be removed?

From here on out I am no longer asking the question. This is my meta-commentary on my question.

Is this okay as is? I fear it may appear off-topic as being too much about story-building as opposed to world-building, which is a common problem I run into when asking questions, but I'm not sure how to make it more clear that I am asking about what this group in power would deem necessary to eliminate as threats without being too vague as to what the rules of my world are, basically. I also propose an answer as well with reasoning to fulfill the requirement of showing that I have done my own research into the subject. Is that okay or is that too much and therefore confusing to my point? Basically: What issues do you see? Or is it fine as-is?

    $\begingroup$ Okay, I'm clearly not understanding your question very well and we're both getting frustrated, so I'll leave it up to other people to give you feedback instead. I've deleted all my previous comments, per your request. $\endgroup$ – Dubukay Jan 17 at 21:46
  • $\begingroup$ My previous response was not out of frustration. I meant it when I said I appreciate the fact you like the question, but I hope you can understand where I am coming from in my replies. I can't fix anything if I'm not told what the issues are; and when you're nitpicking a synonym that is still accurate, it feels pedantic. Please understand I only asked for your cooperation in clean-up as a means of keeping these comments from being overly conversational and if you do have any specific issues with my proposal, please share so I can fix its issues if there are any. I don't want to put this up $\endgroup$ – Sora Tamashii Jan 17 at 22:36
  • $\begingroup$ just for it to be closed in the hour. At the same time, I do appreciate the fact you tried to help, but it doesn't help when everything you say is wildly unrelated to what is being asked. I hope you can understand that I don't mean anything bad in my responses to you, and I understand you did not have bad intentions either... it just felt bad being told that my question has all these issues, but they were all misunderstandings that you openly admitted to not being able to explain where you got those ideas from. Enjoy your day. $\endgroup$ – Sora Tamashii Jan 17 at 22:40
  • $\begingroup$ If the only actual question is in the title, then it looks like imagine contest or guessing game, not objectively answerable question. Or, like @Dubukay, I don't understand it - and "unclear what you are asking" is perfectly valid Vote to Close reason, too! $\endgroup$ – Mołot 21 hours ago
  • $\begingroup$ @Molot, I bolded the in-text question since you seem to have missed it. I also listened to a suggestion another user gave me in Chat as to reduce bloating the question. That said, Molot, the question in the title based on the information in the post would not be an imagine contest/guessing game. I give a bunch of details about the world that is being worked with. If you need more information, please share what I need to add. That said, Dubukay was not misunderstanding due to it being unclear. You seem to realize what the question asked is, but Dub was making up questions and didn't read. $\endgroup$ – Sora Tamashii 10 hours ago
  • $\begingroup$ I am not trying to sound bratty. I get this can come across like that, but I'm just trying to be as clear as possible. Please understand I mean nothing by it. If the question is unanswerable, please say specifically why. Please do not be like Dubukay who was making things up without any basis, though, and then being unable to explain where these erroneous ideas came from. I do appreciate criticism, but please say where the specific problems are and what info is still needed. Please and Thank you. I love constructive feedback and I hope you can provide me some. :) $\endgroup$ – Sora Tamashii 10 hours ago

    $\begingroup$ I'm sorry, but this entire question reads like meaningless word salad. You are using highly specialized terminology from a domain which is dear to you but terra incognita to many others. I feel that I get the gist -- you are referring to a setup similar to John Norman's Gor and its Priest-Kings (the equivalent of your "celestials"), with the players playing the part of Tarl Cabot. If so, then what's the difference between the motivation of the (relatively) well-known Priest-Kings of Gor and your celestials? $\endgroup$ – AlexP 5 hours ago
  • $\begingroup$ @AlexP I am sorry, but I have no clue who John Norman is, what Gor is, and what the Priest-Kings are. Is there something better than this Wikipedia article to explain who they are and what they are about? A quick skim only tells me they abduct humans for... reasons? It makes it hard to understand what they are and what they want and I can't answer your question when I have no knowledge regarding the comparison you made. $\endgroup$ – Sora Tamashii 5 hours ago
  • $\begingroup$ Gor is the anti-Earth, a world similar to Earth but stuck in what looks like the bronze age, with some (pretty low level) magic. Tarl Cabot is an Earthling who finds himself on Gor. The Priest-Kings are superior beings who keep Gor in the bronze age by smiting those who try to develop technology. (And, of couse, this is just the conceit; the books are really about erotic BDSM relationships. But the conceit looks to me to be very similar to what you are asking about. This being the point of my comment: you are using esoteric terminology, so I gave an esoteric example.) $\endgroup$ – AlexP 5 hours ago
