Well....we have to define "medival" first. Is it an advanced sociaty on other aspects? It's a different world, to begin with, so what do we know of it, after all? Is it, indeed, round? Is the atmosphere as ours is or was?

Many variables here, so I'm saying let your mind dictate more how you would perceive it, rather than anything else, until we can read lore that explains it.
