The elemental wards were a set of four magical locks placed on the doors of the abandoned Hammerite cathedral in the Sealed Section of Old Quarter by the Keepers. Each ward represented a specific element, namely air, earth, water and fire, and could each only be opened by a corresponding elemental talisman. The Keepers sealed the cathedral with these wards and hid the talismans in various parts of the city in order to contain The Eye, which was the origin of the catastrophe in the sealed section.

At the time, the elemental wards were a rare instance of the Keepers taking an active and overt role to change the course of events in The City.
