Discussion of the Necropolis faction.

Is this information 100% accurate?

I don't think so. After all, living undead is the last stop before complete nonsense. In "Heroes of Might and Magic V," liches are quite dead! Here are some more links where you can see liches: here is an article about the supposed composition of the race, and here is a post in which Ancient Evil tells me about the lich :). There are artifacts both there and here.
