From Halopedia, the Halo wiki
Like the other legendary Arbiters of old Sangheili past, Irsu 'Labat had forged his path on Sanghelios to become a powerful warrior-ruler of all the clans. A master in combat, 'Labat victoriously vanquished his foes on the battlefield and brought the continent of Qivro under his subjugation. Part king and part judge, Arbiter Irsu 'Labat was a tyrannical ruler whose violent and oppressive regime was later overthrown by a devoted brotherhood of Kaidons, the first original ancient Swords of Sanghelios.
