As preparation for crafting his soul, Athaliah takes Mammon to the Promethean's Demense to explore his Onieros. She instructs him to meditate and he envisions himself driving out of the city into the wild. Slowly he calms and snow begins to fall in his vision. He pushes through and stops at a church letting out from Mass.
He and Athaliah enter the vestibule for his Onieros and he finds himself at a party with Mr. Samuelson. As he remembered many years ago, the old man tried to get him to do a favor for him in exchange for getting him in on real estate. Mammon plays along and eventually leaves the party. As he steps out he finds himself Christmas shopping with his brother, discussing what to get his father and sister. He decides to go shopping for dad first and finds himself in his backyard playing football. After tossing the ball around with his father for a while, he again moves on. As he heads down the street he finds himself trick or treating with his sister. They decide to hit one of the big houses.
There he finds himself in another scene. This time with Dan Frazer, a competitor he conspired with to sell out a friend of his. This time rather than go along with what happened, he tells Dan he would fight him until the bitter end. With that he left his office. On the city streets Mammon heads for the park, wondering where he lost Athaliah. As he passes a jungle gym, he realizes a large number of crows have gathered. After trying to shoo them away, he is attacked and harried into a nearby building.
As he gathered himself together, he was greeted by Mr. Johnson, the Seer who started his Awakening. After playing through the scene, Mammon follows him.
He loses Mr. Johnson at Town Hall but meets a version of himself instead. Dressed in the finery of a powerful mage, this demon convinces Mammon to continue his pursuit of power. Athaliah returns and warns him not to always listen to this being as it knows no bounds. With the journey concluded, Mammon is inducted into the Bene Ashemdai.
