Tem'Bhetek's faction

This faction was primarily composed of Jiralhanae and was led by San'Shyuum. Following the end of the war, those who sided with the Covenant during the Great Schism faced many hardships. The near extinct San'Shyuum had retreated into hiding, while many Jiralhanae continued to wage war against the Sangheili. After losing his family during the fall of High Charity, a San'Shyuum prelate named Tem'Bhetek created the faction alongside Boru'a'Neem to seek revenge against the Sangheili.

Origin
When the Great Schism occurred, the Covenant was divided in two. The majority of the San'Shyuum and Jiralhanae remained loyal to the Covenant while, the Sangheili led the forces abandoned the empire. As a San'Shyuum, Prelate Tem'Bhetek found himself on the side of the Covenant, lead by the High Prophet of Truth. During the battle of High Charity, Tem's family was killed by the Flood invasion, and blamed their death on the Sangheili's interference. Minister Boru'a'Neem promised he would help Tem avenge his family's death if they escaped together. After their escape, they went into hiding as the Covenant's was defeated at the hands of the Sangheili and UNSC forces. Following the war's end, Tem and Boru created a new faction.

Vendetta
This new faction employed species who were on the losing side of the Covenant civil war, and was predominantly composed of Jiralhanae. After being defeated by the Sangheili, this faction sought revenge against their species. Unlike Boru'a'Neem, Tem'Bhetek had a smaller scale, more personal vendetta against Rtas 'Vadum and the Shadow of Intent, as he viewed them responsible for the death of his family. Unknown to Tem'Bhetek, the faction planned to use a prototype Halo installation to genocide the Sangheili species by activating it near Sanghelios. This faction continued the efforts of the Great Schism up until its defeat in 2553.

Military structure
As in the Covenant hegemony after the Great Schism, Tem's faction was made up of the primary member species that remained loyal to the Covenant against the ejected Sangheili.
