King Arthur (Volume 1): King of Winter

What I want to write is the story of my lord Arthur, a long time ago in this land called Britain. He is the god of war, the uncrowned king, and the enemy of God. Most of you have heard of his name, but you have never shed tears for him like I did... The story begins with the birth of a baby. He is the new crown prince of the Kingdom of Demonia, Arthur's nephew, and a weak lame man. He carries the hopes of his grandfather, High King Uther, and is sheltered in Avalon, where madmen gather. He is the favorite of God and the kingdom. However, Arthur, the great Arthur, the true guardian of Demonia, did not receive the justice he deserved. It wasn't until the Saxons invaded in large numbers that the wizard Merlin disappeared from the world in search of the Thirteen Artifacts. The British kings, who had lost their guidance, were shocked to realize that they had already ruined their retreat... Britain, a Britain that has abandoned its faith and is riddled with sins, can, with the efforts of Arthur and Merlin, regain the favor of the gods and return to its former unified glory?
