- Kassandra: Enough games, Hades. I did as you asked. We had a deal.
Labors of the Keeper was a virtual representation of one of Kassandra's genetic memories, relived by Layla Hassan through the Portable Animus HR-8.5.
Kassandra returned to Hades after performing numerous tasks to atone for her killing of Cerberos.
After helping Hades with his tasks, Kassandra returned him at the Passage of Souls. There, Hades sat on his throne while his hounds attacked Kleon. Hades spotted Kassandra approaching.
The hounds dragged Kleon away.
Hades laughed.
Hades rose from his throne menacingly and towered over Kassandra.
Hades leaned casually against his throne.
Hades picked up his throne and threw it towards Kassandra, who dodged it. He brandished his axe.

Hades and Kassandra engaged in combat. Hades unleashed a series of attacks at Kassandra, which included launching several Orbs of Hades, dashing forward with his weapon extended, and telekinesis.
Kassandra dealt significant wounds to Hades.
Kassandra and Hades continued to clash. Hades began conjuring protective auras on his armor to mitigate Kassandra's attacks. The protections were no match for Kassandra, and she wounded him further.

Kassandra defeated Hades, who collapsed to the ground bloody and out of breath. Despite this, he began laughing.
Hades sat up.
Hades picked up his weapon and pointed it skyward. The bridge became encircled with a projection of smoky black shields. Kassandra looked around before turning towards Hades.
With their battle ended and Hades' last gambit to imprison Kassandra in play, she angrily raised her foot to kick him square in the face.
Kassandra fought and defeated Hades after he refused to teach her what he knew about the Staff of Hermes Trismegistus. Hades later trapped her in the realm by projecting a shield around it.
