I don\'t think that there\'ll be a homeland within Yliakum for most races, only the Lemurs and the Kran are the exceptions, them being created here.
Now, cities and such are different. The notion of an underground dwarven city is interesting, but it appears that a large number of them would rather live outside of their mines, venturing into their depths to collect natural resources (At least in my opinion).
As for each race having better access to different resources... Well, it does go for diversity, but the common resources: iron, coal, stone, wood, food, etc. should be at least readily available for each city. The placement of cities are not by chance, usually

Remember, we\'re all \'underground\' here
