Old Torp was an elderly gnokgoblin from a Deepwoods village. He convinced his niece, Mim, and the rest of the gnokgoblins in his village to migrate to Undertown. However, he was badly misinformed about what it was actually like there. He thought that Undertown was a place of freedom and plenty where all their troubles would be ended, but was unaware of the poverty and starvation that were rampant in the city. During the group's journey across the Mire, he struggled and had to be helped by Mim. He was killed along with the rest of the group by their guide, Screed Toe-Taker.
