: Yeah they do. Nothing is added. Where's this from?
Thrall are raised from "the graves and catacombs of a thousand years;" very few thousand-year-old corpses are anything more than dust and bones. So it'd seem that most Thrall actually get somewhat "reconstructed" during creation.
And no, I don't consider time-induced rotting to be direct "mutilation" either. But it *is* another case where creatures must be removed from their fresh, intact-as-in-life state before or during the reanimation process. (Although if you don't buy GURPS, you won't believe that perfectly fresh corpses can't be made into Thrall.) And as such, it falls roughly in the same category as the alterations experienced by Soulless and Wights, and applied by Soulblighter to himself. Even Ghasts always appear in an advanced state of decomposition, although that's probably for artistic reasons. Why such alterations are necessary, I have no idea.
