Aster used a field spell, Clocktower Prison, to fight Jaden with his army of Destiny Heroes. Aster was beating Jaden without mercy. Jaden destroyed the Clocktower with another magic card, but all that did was let Aster summon a more powerful monster, Dread Master. Aster revealed that his father was the one who created the Destiny Heroes, but he vanished when he was younger. Apparently he was kidnapped, and Aster vows to find the kidnapper. Dread Master finished Jaden off, and after he lost, he started to feel faint and his cards started to turn white, not knowing it's because of Sartorius' spells that he lost the duel and the ability to see his cards.
