If the assumption that the Draketooths are evil aligned(due to them stealing children and money from their spouses) is correct, then maybe they cannot be resurrected because they're in hell?

I don't know how the afterlife in D&D works, exactly, but if evil aligned people go to some afterlife where they don't want to be, it would be pointless if they could leave anytime they want, would it?


The black dragon seemed to be happy in afterlife, though...is there no hell in D&D? On the other hand, V seems to fear s/he'll get there...
