Casket

The Caskets are Forerunner artefacts built for combating small, system-wide Flood outbreaks. The devices work by rapidly accelerating the processes of the star of a system, causing it to erupt in a supernova effect, albeit presumably more powerful. The UNSC search for the Caskets in the 26th century was known as Operation: EUREKA.

Known Caskets

 * Casket Iota-03: The first Casket encountered by UNSC forces, discovered buried under the planet Crystal. The discovery of it led to the creation of Task Force Bravo, in the hope of preventing the Covenant from finding them and using them against the UNSC. This Casket was activated in 2551, destroying the system.


 * Casket Kappa-02: The only active Casket found on New Jerusalem.


 * Casket Storage-03: The inactive Casket found on New Jerusalem, in The Armoury. This was taken to Earth in Spartan-I DAB-101's Covenant supercarrier.
