@Duncan_Frost:

Well, you could simply use Late Era Ermor as a base for an undead mod nation in early or mid, mod everything else to your own purposes, and take advantage of the freespawn in that way. However, that would come with the strangeness of getting some ermorian undead (like velites, lictors, etc.), plus some other strangeness.

In reference to your question. Ermor gets basic undead in all it's provinces, more with more dominion. Stronger undead in forts, and stronger undead in temples.

Edit:
Follow up question to everyone:
Is it possible to perform corpse to gem transformation with other gems gained a'la modded ravenfeast spell?
