Kingdom of Camelot

Camelot is the new yet prosperous kingdom to the far south of Britannia led by the current king, Arthur Pendragon who is advised and mentored by the Boar's Sin of Gluttony, Merlin of the Seven Deadly Sins.

Background
Not much is known about the Kingdom but it is said that Uther was once the king of Camelot before Arthur's ascension to the throne and had an alliance with the Kingdom of Liones.

At some point, Arthur became the new king of the country after pulling out the Sword in the Stone that fell from the heavens when no other Holy Knight can pull it out.

Plot
When Baltra suffered a stomach ulcer, Arthur and Merlin returned with him to Camelot to have him treated with a Cure Angel which would eat away the tumor despite the discomfort of the Liones' king.

Later on, Arthur led the kingdom's Holy Knights in defense of their country against a massive behemoth revealed to be Albion that was awakened by the Ten Commandments' return from the Demon Clan's seal.

Trivia
