The Map

The Map is a troll encountered during Death Plateau. He is found in a cutscene during the quest and needs to be defeated.

He can be spoken to, and doing so will reveal that he ate the map leading to the human settlement, resulting in the other trolls getting annoyed with him and nicknaming him "The Map". It's unspecified how much time passed since then, but it's hinted that it was long enough for The Map to resort to Cannibalism.
