From page to king Arthur

Arthur, a sword-servant at the Albion Royal Armory, is secretly a prince. Twenty years ago, King Uther—the ruler of Albion and humanity's greatest dragon slayer—was betrayed by the minister Mordred and met a tragic end on the battlefield. Arthur lived in anonymity while studying magic under Merlin, who revealed that to truly defeat Mordred and exact revenge, Arthur must travel to the Isle of Avalon, compete in the Wizard Tournament, and draw the legendary holy sword. To gain entry to Avalon, Arthur chose to follow Agravain—Mordred’s son—enduring great hardship along the way. He defeated ferocious dragons and rescued Guinevere, all to earn the right to draw the holy sword, exact his vengeance, and lead humanity to victory against the dragons.
