From Halopedia, the Halo wiki
Caius is a notable Jiralhanae leader, presumably a Chieftain. Caius was listed by Castor as a notable leader alongside himself, Palaemon, Lydus and Hekabe as potential leaders to rally the pious ex-Covenant Jiralhanae around, though ultimately dismissed as not having the power base to have done so.
