Gwydion is accidentally summoned by Zatanna when she performs a spell to summon the man of her dreams. He follows after her, and when she engages in a séance with several other people he tracks her into the Imaginal World and the Never-Be-Found Realm. He burns those who are participating in the séance, leaving Zatanna physically untouched, but without her powers. He continues to follow her, tracking her to Cassandra Craft’s shop. He attacks, taking on several shapes in his battle with Zatanna, who successfully traps him in a jar. He remains in the jar until Zatanna unleashes him against Zor. She orders him to mimic Zor, and he does so until he is broken by Zor. He survives the battle and is returned to his jar. She him again unleashes him during the battle against the Sheeda to reinforce her spell drawing the Seven Soldiers together. His fate is unknown.
