Kingdom of Liones

Britannia is a kingdom that was formerly ruled by the family of Lyonesse before a coup d'etat at the hands of the Holy Knights, which made it a puppet state. The kingdom had an alliance with the fairies before the burning of the Fairy King's Forest.

Background
Britannia is a large and powerful country which is protected by its knights and the Holy Knights. The Seven Deadly Sins were once an active group of knights in the kingdom before being framed for the murder of the Great Holy Knight Zaratras.

Plot
Since King Lyonesse, although realizing that a predicted Holy War would soon occur, ordered all the Holy Knights to lay down their swords in an effort to avoid war. However, the Holy Knights, believing that the war was inevitable and that protection of Britannia was their duty, captured the king, with the current Great Holy Knights, Hendricksen and Dreyfus, assuming command. They also started enslaving and forcing the citizens to participate in military efforts while justifying their enslaving with the fact that the citizens were being forced to do something for their own protection.
