Chak 'Lok, a Sangheili Warlord and former Covenant Evocati member, joined the Banished. Calm and polite before battle, he became ruthless during combat, enjoying torturing prisoners. Arrogant and prideful, he disdained humans, viewing them as weak, and held the Jiralhanae in contempt despite his loyalty to Atriox and Escharum. He revered the Harbinger, believing her words to be true.
