So I need to ask a question that needs historic (History) and linguistic (Language) elements answered that influence each other in a world building setting... Should I ask the question in all 3 stacks and reference each other, or just world building even though I'm not likely to get a properly informed answer, or linguistics where it is the best place to ask to get the information I want, but it is non-factual question which means it probably doesn't belong there...
As ask in the comment section. Basically, at two points in history a bunch of portals open up on Earth and groups from all over Earth and transported to a new world (in two different spots on this new world at 2 different times)... I need to know generally what would happen, assuming set of them survive and create their own civilizations. So I need to know what civs are there in those times and how they'd react to people of other civs...or at least a best guess... This is a question that needs a bunch of History elements to contruct the world, but then I also need to know what elements of the languages these civs speak would transfer to this new language... which requires the history and world building elements.
The history bits world building might be ok to cover, but the linguistic parts I don't think world will answer satisfactorally...
