Camelot was the castle of King Arthur, the ruler of Albion. It was a beautiful castle standing at the foot of a mountain in the center of the kingdom. After the death of Arthur as a result of the battle with the Morrigan, his sister Morgana ruled in his place.
Camelot has long since been lost to time and Albion eventually became Great Britain. In present day, the existence of Camelot is regarded a myth.
