Tartarus

Tartarus was the last appointed Chieftain of the Jiralhanae and military chief to serve in the Covenant. He acted as the Hierarchs' chief enforcer and, more accurately, the High Prophet of Truth's second-in-command. Tartarus was responsible for enforcing Truth's changes to the Covenant which caused the Great Schism, the civil war that led to the dissolution of the Covenant empire. In the final weeks of the Great War, Tartarus attempted to activate Installation 05 to begin the Great Journey, but he was ultimately killed by Arbiter Thel 'Vadam with the help of Sergeant Major Avery Johnson.
== Biography ==
=== Early military career ===
Tartarus started life as the nephew of a venerable and religious pack leader known as Maccabeus on Doisac on July 8, 2491 and was a member of the Rh'tol skein. He took on the childhood nickname of Tartar. Wearing the scarlet armor of a Jiralhanae Captain, the young Tartarus served as the security officer of his uncle's crew aboard the armored cruiser Rapid Conversion. He was known to have an awkward, somewhat-cordial relationship with the ship's attached sangheili observer, Savel 'Dhuralee, who held a degree of personal respect for the jiralhanae's prowess as warriors that many members of his species lacked.
Soon the unggoy Deacon Dadab and his companion Lighter Than Some found themselves on board the Rapid Conversion after escaping the destruction of the kig-yar missionary ship Minor Transgression.
