This article is about the Sangheili. For the Covenant naval category, see Covenant fleet#Ship classification.
During the Human-Covenant War, the Sangheili warrior known as the Executioner was given command of a contingent of Jiralhanae on Algolis during the siege on the planet. Following Atriox's return from another suicide mission, the Executioner expressed his concerns to the High Prophet of Truth about Atriox becoming an unpredictable threat, given his continued survival and rising influence among his peers. Hoping that he could still be of some use to the Covenant, Truth asked the Executioner to find out if Atriox was still loyal and faithful. After learning that Atriox was becoming aggressively resentful of the Covenant's orders, Truth tasked the Executioner to dispose of Atriox without turning him into a martyr. The Executioner then arranged for a loyal Jiralhanae pawn to tail Atriox in order to capture him in an act of open dissidence. During an assault on a human fortification, the Executioner observed Atriox closely from an eye's surveillance. The loyal Jiralhanae soon confronted Atriox when he made a blasphemous remark. In the ensuing confrontation, both Jiralhanae warriors attacked each other, and their fight ended when Atriox murdered the fellow soldier. Upon Atriox's return, the Executioner met and encircled him with a group of other Sangheili. Realizing what was intended, Atriox surrendered his Type-2 gravity hammer and dropped to his knees. The Executioner pronounced him a heretic for slaying his own comrade and sentenced Atriox to death for his betrayal. As the Executioner thrusted his red-bladed energy sword toward Atriox, Atriox caught the blade with his right hand and then killed the Executioner with his own weapon. Other Jiralhanae then followed Atriox's example and attacked the remaining Sangheili.
