The spell can even provide a new body if the original no longer exists, in which case you must speak the creature’s name. The creature then appears in an unoccupied space you choose within 10 feet of you."

So is a dead zombie a dead undead or just dead? Do you have a good source for that?

Moving aside from zombies for a second...

Reading these spell descriptions, suddenly I have a sinking feeling they had a reason for choosing 200 years as the exact amount of time Astarion has been undead. :O What if we have to somehow resurrect him as a normal living elf but can't because he's technically been dead/undead just that little bit too long? Aaaaaagh! (Theorycrafting angst is the worst.)
