Uxsa 'Teaumee was a distinguished Sangheili whose contributions and services to the Covenant Hierarch had revealed an inconvenient truth which led to the dissolution of the Covenant Empire. Once a strong believer of the fulfilment of the Great Journey, Uxsa submitted himself into the Covenant Army and devoted most of his spare time understanding the way of the gods. When the Human-Covenant War broke out between the Covenant Empire and the human civilisation, Uxsa would take his place in the Council of Generals' Special Operations Warfare, and served alongside his brethren on a number of war theatres. Nearing the second indiction of the Ninth Age of Reclamation, Uxsa would join the Obligation of the Priory.
