Race Metamorphosis!!

How do you give them mountains? After all, mountains are not available as a landscape type, and Dwarves have 2 native terrains - snow and Dwarven dungeons. And the Mages were unnecessarily made based on Eastern fairy tales, and in general, why did Nival come up with stereotypes for races based on real life? After all, people play games to relax and forget about all sorts of problems, but here you have people and mages; it would have been better to make them Greeks, and that would have looked better.
