Fate of the Duegar

[Keltest]

For some reason I forgot what Duergar are and thought they're half-vampires.

I suppose half-vampires are impossible in OotS-verse.

Unless you managed to kick out the negative energy soul living in your body, or it tore in half, or...?

I don't know. Unlike a lich, a vampire clearly has hydrated, non-decaying flesh, which implies a lot of their bodily functions still work. Heck, Greg and Malack can still breathe, they just don't need to. I wouldn't count on a vampire getting pregnant (that much negative energy is probably bad for a baby), but without knowing how much their bodily functions have been replaced by negative energy (as opposed to supplemented by it, like with breathing), its possible they could still have children with living beings.
