Blacksmith Arthur is secretly the Red Dragon King. After five years funding fiancee Elaine's studies, she publicly crushes his ring and dumps him for Lord Kendrick. Princess Guinevere, fleeing a forced marriage to warlord Duke Fletcher, turns to Arthur. In palace halls and at the Holy Dragon Altar, he shows terrifying power yet hides his identity — until Archmage Merlin kneels and Arthur draws Excalibur, unleashing golden light and a spectral dragon's roar that shatter five years of silence.
