Are we treating this separation as being unique to vampires? That is to say, is there a difference among Xykon (living person), Xykon (dead body - when visible), and Xykon (animating lich essence - when speaking)?

Likewise, are Silver Dragon and Zombie Dragon distinct characters? Lirian and Zombie Lirian? Is the Crystal Golem enough the same (both body and spirit) to be considered Crystal?

Not quite the same, but related - I had been considering The Dark One (goblin) to be the same as The Dark One (god), but maybe they are different enough.

I’m not sure of the right answer (or best answer, I guess), but just some questions to get us thinking.
