From Halopedia, the Halo wiki
Keza was stationed on board the Unwavering Discipline at the onset of the Carrow Conflict and the issuing civil war between Rojka 'Kasaan's faction and Thars 'Sarov's forces. He survived its crash landing as Rojka pursued Gray Team to the surface of Carrow. In the wreckage, Keza decided that Rojka's leadership would kill them all and therefore made an attempt on the Kaidon's life with an Energy Sword. He failed at this and was subsequently killed by Rojka 'Kasaan, who shot him in the head with a Plasma Pistol.
