Sorry for delaying so much on getting this map 'update' (read: scribble I sent Wrongend to get him up to speed on where shit is) out, but here's the world prior to the Frontier:
White stuff is sea ice, averaged through the year. There'll be more in winter, less in summer, and land ice will be more extensive around those latitudes. Blobs near the citadel are, from north to south, prairie, forest and swamp. Red spot in the southern continent is the Temple of the Book, yellow spot is Aella's retreat.
@Frettzo The Frontier squashes most of the purple grass, and a river. You can reconcile this how you'd like, but it's probably best if the purple grass survives around the oases and the not!Nile river.
