Biography

 * Fought in the first battle of harvest, killed the previous chieftain, his uncle Maccabeus, to take control.
 * His rise to power occurred because he was able to integrate the Covenant religion into the traditional tribal structure. Also his success on the battlefield inspired the brutes by showing that they can be just as capable as the Sangheili.
 * Healed the resentment between the Doisac brutes and their offworld cousins that had been taken by the Gryunjalla. Turned their hatred towards the Gryunjalla proper and the Sangheili.
 * Tartarus saw the Jiralhanae history as subjugation after subjugation. Saw it as their right to emerge on top by defeating all their foes.
 * Upheld the ideals of Jiralhanae strength.
 * Tartarus didn't see the Covenant as subjugators, but as a way to empower the Jiralhanae. Controlling the Covenant would give them a mighty empire needed to finally achieve a top spot in the galaxy.
 * Pushed major reforms that evolved the Jiralhanae armies from tribal militaries that relied on the strong defeating the weak, into a regimented military force that borrowed lot of ideas from the UNSC. His reforms were built around the idea of finally defeating the UNSC, and had a very high military-to-population ration.
