After that, the protagonist escapes into the woods with Sam Greenwood, who reveals himself as a satyr.
As they are being chased by another Leonte, Ms. Roche's brother, Sam tells Zane about his demigod identity and leads him through the woods to an abandoned library that will provide temporary sanctuary due to being the sacred place of Mnemosyne.

After the Leonte breaks in the library and is defeated, Mnemosyne appears, thanking Zane for cleansing her library, and offers him a gift and the advice to travel to Austin in order to discover his godly parent.
In Austin, Zane finds the River God Barton and asks him for advice, but he isn't of much help. Zane then meets the Goddess Columbia and she does offer aid. His goal is to retrieve a valuable object from the lair of demon cannibalistic satyrs. During the quest, his godly parent talks to their child inside his head. Once Zane gets the object in question, the godly parent requests that he go to New Orleans.
