Aun'El Shi'Ores was a member of the Ethereal Caste of the Tau Empire. He served as the commander of the Tau forces sent to secure and hold the world of Kronus. He, along with Shas'O Kais, was the leader of the Fire Caste forces sent by the Tau to protect their colony on that world and bring the wayward planet back into the Tau Empire's fold. In the non-canonical ending of the game where the Tau win the campaign the Imperium of Man came to call the Dark Crusade, Aun'El Shi'Ores, with the help of his Fire Caste commander Shas'O Kais, expels the 6 other races' forces from Kronus and brings the planet into the Tau Empire, making the world a full Sept of the Tau's Third Sphere Expansion. But in the canon outcome, during the invasion of the city of Or'es Tash'n, the Ethereal was quickly targeted by the Imperial forces of the Blood Ravens Space Marine Chapter who sought to deal a harsh blow to Tau morale. Given that the Blood Ravens' ending is the canonical version of events on Kronus, Aun'el Shi'ores was killed in the assault on Or'es Tasn'n, despite being heavily guarded within the Tau citadel and surrounded by his elite bodyguards. His corpse was recovered by Shas'O Kais, who was emotionally shattered by the Ethereal's death, before it could be seized by the victorious Space Marines and taken back to T'au for burial as the crumbling Tau forces fled the planet.
