"The Hierarchs have violated the Writ of Union, they have killed many of our brothers! We must resist against the Jiralhanae and make the Prophets pay for what they have done! I ask you to fight by my side and we will bring honour back to the Covenant!"
―Jek at the start of the Great Schism
Jek's faction was a Covenant splinter faction formed by Sangheili commander Jek 'Nrahom at the start of the Great Schism.
After returning to High Charity from Solemn Penance on Installation 05 and witnessing the Changing of the Guard, Jek immediately came to the conclusion that the Hierarchs violated the Writ of Union and when the Covenant Civil War started, he rallied his own group of Sangheili, Unggoy and Kig-Yar to fight against the Covenant Loyalists led by Jiralhanae.
