Kor'o Y'eldi (his name roughly translating as 'the winged one') is a Tau Air Caste High Admiral. One of the most celebrated commanders in the Air Caste, Y'eldi is a veteran of many battles though he was born too late to take part in the Damocles Crusade. Despite this, Y'eldi has made it his life's work to study the account of the war in an effort to better combat the Imperial Navy, which he views as the principle threat to the Tau Empire. He will personally oversee the upgrading of warships to better fit unique regions, opponents, and circumstances. Initially given command to explore the Jericho Reach region, High Admiral Y'eldi now commands the Mal'caor Fleet to combat the Imperial Navy in the Achilus Crusade.
