Minion

"Minion" was a Dimensional Pirate tasked with locking the crew behind the 5th Door and hiding the keys with each Dungeon's Guardian. They were supposed to release their crew within a months(?) time, but was killed by Crazy Pete which doomed the Dimensional Pirates to being trapped behind the 5th Door.
