The grand citadel is alive with excitement as the Prince's birthday festivities approach in this enchanting tale. However, Arthur's former foe, Odin, vows to make this an unforgettable event for Camelot—because hidden among the guests is a lethal assassin ready to make their move. In the aftermath, Camelot finds itself in ruins. Merlin faces a difficult choice: how far will he go to mend the situation? Is he truly willing to jeopardize everything and expose his deepest secret?
