Rome is flooding from places water should never reach.

Sealed archives. Forgotten vaults. Rooms built to preserve memory and shelter the living. One by one, they begin filling from the inside.

When Elizabeth and the Guardians uncover a broken piece of the ancient Covenant Seal, they realize the flood is not only water. It is a warning. The restraint that once held judgment inside its boundary is failing, and the first places to answer are the places where human memory is kept.

Cassian has spent his life preparing for collapse. His foundation rescues archives, funds preservation, and offers protection when governments move too slowly. But Cassian does not want to save the world. He wants to decide what deserves to survive it.

To stop him, Elizabeth, Hassan, Amira, Nabeel, Al-Hadidi, and Khalid must follow the scattered witnesses of the Covenant before Cassian completes the Seal for himself. Every step draws them deeper into old flood traditions, drowned chambers, and the terrible question at the heart of survival.

Who gets saved when the waters rise?

And who decides?
