Usze 'Taham:

Debuted in Halo 3

Born Oct. 31st, 2519, Usze was fathered by the famous swordsman Toha 'Sumai (although only knew him as an uncle that would act as a trainer) and born into a respected merchant family in Sumai keep. He would graduated with honors from a top war college, being posted on the Fleet of Faithful Ardor afterwards. After only a single tour within the fleet, he would be offered a place in the Covenant Honor Guard, but declined out of the desire to start away from ceremonial positions. He continued to refuse offers, which could have put him in danger of accusations of apostasy; but, either due to luck or superiors protecting him, Usze would not be targeted, save for some assassination attempts. His actions during the Human-Covenant war would ultimately cause those wishing him in the Honor Guard to finally back off. Still prior to the Great Schism, Usze would join the Ascetics and serve as a liaison for the Covenant, while also serving under SpecOps Commander Rtas 'Vadumee. Once the Great Schism broke out, he would join the Separatists' Fleet of Retribution, specifically the Special Warfare Group. He would then head to Earth alongside the Arbiter and N'tho 'Sraom. Later, he would take part in the Battle of Installation 00, even being present when the Master Chief deactivated the Halo Array and the Arbiter killed the Prophet of Truth.

At the end of the war, he would become a liaison to the UNSC and an emissary within the Ascetics' naval forces. He also liaisoned between feuding Sangheili keeps and factions, while also helping to resurrect the Ascetic Guard. Upon joining the Swords of Sanghelios, he helped establish the Riftborn: a SpecOps division fully committed to joint operations with the UNSC. In 2555, he learned of an assassination plot against the Arbiter and confronted the would-be assassin, Otar 'Bemet, refusing his attempts to get Usze on his side and killing the rebel. Once that was finished, the Arbiter informed him that the UNSC discovered the Halo Array was suddenly ticking down to activation, so he would be sending him alongside N'tho and the Mayhem to help stop it in Operation: FAR STORM. While waiting for the portal at Voi to be reactivated, he watched over the Huragok Drifts Randomly. When Drifts finally activated the portal, a Forerunner Retriever suddenly appeared and attacked. A meeting would then be organized on Mayhem. The Sangheili wished to continue on with the operation immediately, but Captain Annabelle Richards claimed they needed to wait for consent due to the unknown threat to Earth. Yet N'tho had foreseen this as a possibility, revealing he had tricked the humans necessary for the operation to be on board Mayhem and that he had already decided he would be heading into that portal with or without approval. Another Retriever would attack just then, but Mayhem took care of it before entering the portal. To their surprise, they found the journey took a matter of hours rather than the usual two weeks. Multiple Retrievers were waiting for them, causing Mayhem to crash on the Ark. Usze would then join an expedition on foot, only for a pack of Blind wolves and a group of Chaefka to attack and Olympia Vale to become separated from the group. The team would split up, with Usze, Spartan Elias Holt, and Henry Lamb following Vale's footsteps in the snow. Communications with the other team would then be lost, with increased snowfall sabotaging efforts to follow Vale. Therefore, they decided to head to the Citadel in the hopes they'd regroup with anyone. Forerunner armigers and a giant carnivorous planet would be among the obstacles the trio faced on the way. Once the whole team - barring the still missing Vale - regrouped at the Citadel, the Halo Array was shut down only for more armigers to attack. Usze, Luther Mann, Henry Lamb, Drifts Randomly, and Kola 'Baoth would retreat down the same elevator shaft Usze used as an escape route the first time he was at the Ark, while the rest of the team were teleported elsewhere by the Ark's monitor, 000 Tragic Solitude. In the inner tunnels of the Citadel, they would discover the central power station, where Drifts would start repairs while Lamb was killed by a Sentinel. They would continue to search for an exit, finding a heavy, locked door blocking their path. Usze and Kola would lift the door enough for Luther and Drift to enter, but would be forced to wait on the other side, becoming open to an armiger ambush. As they fought off the armigers, Drifts would finally take control of the Ark from Tragic Solitude, who would be destroyed shortly afterwards. With the galaxy now safe, everyone - including the recovered Vale - returned to the Mayhem and waited for reinforcements to arrive and bring them back to Earth. Following the end of the mission, Usze would have a heart-to-heart with Vale regarding her failure to negotiate with the rampant monitor.

By 2559, N'tho continued to assist the Arbiter. Notably, he helped escort the Arbiter to and from a meeting shortly after the destruction of the Jiralhanae homeworld Doisac, only to be stopped by Created armigers and forced to give up his weapons whilst they searched their vehicle for the perpetrators of a recent conflict. Later, when they returned to Vadam keep, Usze would be present - along with Kola - in hearing out the Oath Warden Crei 'Ayomuu regarding the existence of a weapon that could defeat Cortana.
