Ethereal - Notable Ethereals: Aun'El Basel'kyth - Suspected by the Imperium to be the head researcher/philosopher of T'au forces in the Jericho Reach, Aun'El Basel'kyth is currently thought to be located in the Beldar Academy on the planet Tsua'Malor.Aun'Ui Kol'denh - Aun'Ui Kol'denh is a social engineering advisor for T'au forces in the Jericho Reach. He has a personal armoured anti-grav unit with a life-support system, possibly due to deteriorating health, and is currently thought to be located in the orbital installation Iphigenia.Aun'El T'au Ko'vash - Aun'El T'au Ko'vash was an Ethereal captured by Imperial forces and held captive by Planetary Governor Severus on the world of Dolumar IV. He was eventually freed by Shas'la T'au Kais but captured again the same day and killed by the heretical Governor Severus.Aun'Ro'Yr - Aun'Ro'Yr was the Ethereal who accompanied Shas'O Or'es'Ka during the Kaurava Campaign.Shas Aux'Phan - Shas Aux'Phan was a T'au Ethereal who died during the Auxion Campaign at the hands of the Dark Angels Ravenwing Grand Master Sammael.Aun'shi - A modest hero of many battles, Aun'shi longs for peace but is bound by duty to his comrades to wage war. Lionised by the Fire Caste, he is seen as a sure sign of victory upon the battlefield, and is greeted everywhere he travels with many salutes and deep and respectful bows.Aun'El Shi'Ores - Aun'El Shi'Ores was the accompanying Ethereal of Shas'O Kais during the Dark Crusade to take the planet Kronus. He was killed by Blood Ravens forces, but his body was retrieved by Shas'O Kais and returned to T'au for burial.Aun'taniel - Aun'taniel was the head Ethereal of the T'au colony of Ka'mais. When a Necron fleet destroyed the Tyranids of Hive Fleet Gorgon about to consume the world, Aun'taniel went out to greet the colony's saviours. In this first contact scenario between the T'au and Necrons, Aun'taniel was subsequently killed.Aun'la Tsua'Malor Vior'la - Aun'la is a low-ranking Ethereal Caste member who was captured by a Deathwatch Kill-team from a courier craft in-transit. In an exceptionally tricky operation undertaken by Battle-Brother Pellas, the Gladius-class Frigate Thunder’s Word slipped deep into T'au-controlled space and intercepted the Aun's craft as it passed through an uninhabited star system. Precision weapons fire crippled the smaller ship's drives and a boarding party easily overpowered the xenos inside. The courier craft was rigged to suffer a catastrophic drive failure and the Thunder’s Word disappeared into the void without sighting any other T'au voidships. As far as is known, the T'au are unaware that the Aun has been captured and believe him to have been killed in the accidental explosion of his ship.Aun'O Tsualal - An Ethereal strategist for T'au forces in the Jericho Reach, Aun'O Tsualal is currently participating in combat in the Velen battlezone of the Greyshell Front. He is the overall commander of all T'au forces in the region and on Tsua'Malor, and his armoured grav-unit always has a Fire Caste bodyguard and Shield/Gun Drone squadron protective detail at all times.Aun'Va - It is said that Aun'Va, Master of the Undying Spirit and the most recent Ethereal Supreme, was the oldest and the wisest of his caste. He had counselled the greatest leaders of the T'au for longer than any can recall, and his hand was seen at work behind much of T'au history. He was the most senior Ethereal upon T'au, sitting upon the councils that ruled not just the Sept but the entire empire. His word was heeded by every member of his caste, for his council had ever proven wise and true. He eventually met his fate at the hands of a Culexus Assassin, who was sent to the beleaguered Imperial world of Agrellan Prime as a part of an Officio Assassinorum Execution Force, which occurred during the Second Agrellan Campaign.Aun'Vre - Aun'Vre was the Ethereal who accompanied Shas'O R'myr during the Taros Campaign, helping to oversee the T'au conquest of the planet. He was killed by the death explosion of an Eversor Assassin within the T'au command centre, though his death sparked a vengeful counterattack by the T'au on the evacuating Imperial forces.Aun'Wei - Aun'Wei was an Ethereal Supreme and the predecessor of Aun'Va. He oversaw the Second Sphere Expansion of the T'au Empire. After a long rule, Aun'Wei chose Aun'Va as his successor and undertook the Last Walk, the ceremony where an ancient member of the Ethereal Caste disappears forever within one of their mysterious temple-domes.
