The Fisher King, a sorcerer who lived many hundreds of years ago, fought many battles in his time, but eventually he was wounded; his injury festered and the infection spread, not just through his body, but through his land as well. His mighty kingdom was reduced to a wasteland, and it has remained that way. According to Gaius, the people of the north call this area the Perilous Lands and few who have ever ventured there have lived to tell the tale.
In order to prove himself worthy to be king of Camelot, Arthur entered the Fisher King's realm to retrieve his Golden Trident. Morgana gave him an enchanted bracelet containing an eye of the phoenix, which would suck the energy from him until he was dead. In the Perilous lands he nearly drowned in a puddle of mud and fought two wyverns in the King's Dark Tower. Luckily, Merlin and Gwaine had set off to save him, and soon they were at his aid. Merlin confronted the Fisher King himself, before bargaining the Phoenix Eye for the Avalon vial. The Phoenix Eye killed the Fisher King, granting him his last wish (The Eye of the Phoenix).
