Oh thanks, that's something I didn't think of! Yeah, the idea is that Pangea got 'torn off' the globe of Alusia, so a great mass of land was removed from the globe, and earth would get their own globe. It's of course a fantasy story (with lots of magical characters) so there's room for a little bit of imagination on the formation of the lands. But I'll keep this in mind for the terrain hights in the legend!
