Lok leads the Huntik Foundation against the Betrayer, but his titan, Demigorgan, is far too powerful. Lok must learn to invoke the legendary titan of champions to defeat it.
The team revisits Lok's mother's home in Ireland, where they are drawn to the mythical city of Tír na nÓg. There Eathon instructs Lok in Willblade combat.
When the Ring of Arc disappears, the Huntik members head back to the catacombs to find it. While underground, they are trapped inside horrifying dream worlds.
