From Halopedia, the Halo wiki
Bomarus is a Jiralhanae serving in the forces of the Banished on Installation 00.
By mid-2559, Bomarus was part of the Banished force involved in the ongoing war on the Ark. In late June or early July of that year, Bomarus was one of several pilots assigned to a raiding party led by Chieftain Minas with the goal of conducting a raid on the grounded keyship, Anodyne Spirit. Bomarus piloted one of the Banished Phantoms involved in the raid, and ultimately survived the battle with the Covenant loyalists inhabiting the keyship.
