The Lord is more alive than dead

Only the Cloak of Death's Shadow, perhaps (since a quest for the Vampire Guards is tied to it). The other artifacts were pocketed by Markal. He spent most of his campaign obtaining the set - the Amulet alone took him at least a whole mission to acquire, and the Ring of the Unrepentant - just as long. My map is tied to the Nival storyline, and it would be strange if Nicholas found all 4 artifacts at the nearest smuggler around the corner)
