What, nobody popping in to claim one or more of the fantastical nations of the New World of this barely-fleshed-upon idea? For shame, my good sirs(and/or madams)! I for one would not mind making and playing a probably-villain possibly-neutral unlikely-heroic Fantasy World faction if everyone else is a'ight with the idea:The Kingdom of Dentora, a ancient nation built upon the backs of the endless ranks of the dead. Lying in the heavy wastelands and ruined cities of the heartlands of a once great empire, entrenched within a terrain that seems to actively blight foreign conquerors and provides little in the ways of spoils useful to the native living-namely, food and farmable land necessary for a protracted occupation. Probably universally despised for naturally being who and what they are by the nations of their native world...But, lets be frank with ourselves. The governments of our mundane world tend to be just a little less scrupulous about such matters, especially when a nice profit can be bartered.
May, maaaay or may not have heavy vibes of Ermor, Ashen Empire of the Dominions series and other such undead empires. Because Necromancy is cool.
