Erik the Well-Read - S2.E8

When the Stone of Breezebrain goes Missing, Erik the Well-Read, an historian and Viking, comes to Camelhot in search of it. Unfortunately, Sir Loungealot just catapulted the stone to Castle Threadbare, and it's now lodged in Evil Knight #2's head, singing clues to Count Geoffrey, leading to the whereabouts of the legendary Breezebrain Treasure.
