Dragons ambush the human border army led by the Knight Captain. Up on a cliff, Merlin assigns Arthur his final training test. Arthur equips his armor, rides down on his horse, and traps the main dragon in magical chains. He destroys the beast with a giant sky sigil. The Knight Captain asks who he is. Arthur announces his royal lineage and departs. Merlin tells Arthur he must enter the royal palace to join a tournament.
Ferocious dragons ambush human soldiers on the border battlefield. The monsters blast frost and fire across the front lines. The Knight Captain watches helplessly as the assault decimates his defending army in moments.
Merlin stands beside his apprentice on a high cliff above the fighting. He tells Arthur that this battle serves as his final test. Arthur must conquer the dragon and rescue the surviving soldiers below.
Arthur dons magical armor and leaps into the canyon on his horse. He binds the giant dragon using glowing chains. Above the field, Arthur calls down an enormous sky sigil that blasts the beast with destructive power.
The Knight Captain drops to his knees before his savior and asks for his name. Arthur declares that he is King Uther's son and the future ruler of Albion. Arthur then teleports away from the field.
Arthur meets Merlin on the cliff. Merlin praises his victory over the dragon. He tells Arthur that claiming the King's Sword requires winning the Grand Mage Tournament, which only nobles from the palace can enter.
“This will be my final test for you. Go, Arthur. Conquer the dragon, and show those men exactly who led them to victory.”
“I am the son of Uther. Arthur, the future king of Albion!”
“Every three years, the Alliance holds a Grand Mage Tournament. Win it, and the sword is yours. But only nobles are allowed to compete, so you have to go back to the palace.”
Merlin explains that overthrowing Mordred requires the King's Sword. The weapon belongs to the winner of the Grand Mage Tournament, an event strictly reserved for highborn nobles. Arthur must leave his secluded training and return to the royal palace in secret. Can Arthur slip back inside the lion's den without Mordred discovering his true identity?
