The Talisman of Water is one of four keys that are necessary to open The Haunted Cathedral doors in the mission of the same name. In Thief: The Dark Project, it was hidden at the bottom of a flooded chasm in the burial chamber of Va-Taraq. It and the Talisman of Fire are to be retrieved in the mission "The Lost City". In Thief Gold, the Talisman of Water was instead kept in a Keeper shrine in the network of aquatic tunnels beneath Old Quarter. Previous to the mission "Song Of The Caverns", it was discovered by Captain Colliard and his men on their expedition through the sewers and brought to Valerius' Opera House.
