Questions about the Might and Magic universe.

I don't know for sure, but I assume they are immortal.

I doubt they are immortal, especially considering the words from Sar-Elam's manuscript about necromancy, found by Belket: "For Asha is the goddess who created the world and gave it its name, and she is all the facets of the wheel of existence; a threefold entity of birth, life, and death...."
But if they are indeed immortal, then such characters as Michael and the remaining Faceless Ones should still be alive, right?

These are too complex questions for this universe. Most likely, such things are not even considered.

It's a pity that they aren't considered, because this question interested me the most. :)
It would also answer the question of whether angels and the Faceless Ones are immortal.
