That's pretty much it. I may be missing a very basic tutorial-type section where this is probably explained. But I have checked! And found nothing. If there is actually something already written, please point me towards it so I can better understand.
That said, I am opening this question because I mostly participate in the Worldbuilding stack, but for my latest question I've received points in the Biology, Fantasy and Meta stacks for some reason. Thanks in advance for helping a newbie understand! :)
