The undead that pirates now encounter in the ruined Rat's Nest were once the peaceful citizens of Rott's former home. But, Rott had struck a deal he could not undo. But as Sandra Tew of the Marceline had cursed the undead to stay in that location, Rott could not deliver the promised armies to Jolly, and so he was enslaved into serving Jolly. He had a life-long grudge against Captain Walter, whom he considers as his worst enemy. This was because Walter confronted Rott on his part in the fate of Minertown.
