[QUOTE="Mustrum_Ridcully, post: 8426797, member: 710"] A shell world doesn't really sound like somethin that occurs "naturally", so I think some magic or unusual non-realistic physics are bound to exist - maybe there simply are no asteroids like that in this universe, or something that protects the world - maybe the Gods, or some other, more alien supernatural or technological beings. Maybe one time that protection was broken, and so an asteroid crashed, and there is actually a sea that's slowly but inevitably being drained. Which could be the cause of a big struggle and/or migration. That could be something that's ongoing, or somehting that happened in the past. Maybe someone intervened - gods, mages, engineers - to close the hole again and stop the drain. But in the mean time, land bridges opened up that enabled contact between groups that never had contact before. I am kinda partial over all to keep the oceans and continents as large as on Earth, I think. That means they are not unsurmountable obstacles by non-magical means, but still really challenging. The different oceans would be seperated from each other (so you could feasibly have a few drained). Empires spanning multiple continents would still be impractical, unless you have reliable means of magical communication or transportation, since otherwise a revolution on another continent has alread exchanged continental leadership before the leaders of the other continent could respond. But an interesting question - assuming human migration patterns as they were, but Earth was 11 times larger, but with continents and oceans the same size as now - how far could we have spread until, say, the 5th century or the 15th century? WOuld we have probably populated all continents, or would still some be left alone? How long ago could they have been settled by some humans? Maybe the humanoid species all hail from the first settlers and changed due to the continents they live (be it by evolution, genetic manipulation or magic?). A drain event could be the cause for some recently increased contact between groups that had no contact before. [/QUOTE]
