The Jiralhanae (Latin, Ferus Servire, translated to "Wild Slave") (Second Human Empire: Duiiu'wuin Viuy'yuui), known by humans as Brutes, are the most recent members of the Covenant. They are a large, bipedal, giant ape-like species from Doisac. The Jiralhanae were the second Covenant species encountered by the humans following the Kig-Yar raid on the freighter This End Up. They were also the first Covenant species encountered by the Harvest Colonial Militia. The Brutes have an extreme hatred of the Sangheili, unmatched by any other feud within the Covenant, fueled by the Jiralhanae's natural aggressive nature and the Sangheili's attitudes of superiority. although most of the Jiralhanae stayed loyal to the Covenant Empire, a sizable portion sided with the Alliance (under the banner of the United Alliances of Orion Species).
