Harrison Steele/New Timeline

Fleet Captain Harrison "Harry" Steele is an Human Imperium military official who has served as the 1st Imperial Governor of Buran, and Fleet Captain of the First Imperial Fleet. 
Steele was a member of the Galactic Union Military during the war, where he served on Buran with his younger brother, Arthur Steele. Narrowly avoiding death, Steele continued to fight on Buran for a number of years. When the military coup was launched by Fleet Admiral Kaiser, Steele became a vocal supporter. Eventually, Harrison and his younger brother were renowned enough in the Union to reach the ears of the new Military Regent, Tiberius Kaiser. 
Kaiser, with the help of SPEC OPS, devised a strategy to use stealth to travel to Zultan Prime. There, anti-matter devices would be detonated beneath the crust, decimating the Zultan's homeworld. The operation, under the command of newly promoted Captain Harrison Steele, went exactly as planned. The decimation of Zultan Prime, the holy world of Kulahmai, demoralised the Zultan people and crippled their leadership. 
Captain Harrison Steele and his younger brother, Commander Arthur Steele, recieved commendation for their leadership in the operation that ended the war. The Military Regent, Tiberius Kaiser, promoted both Steeles in rank. Harrison Steele became the first and only Fleet Captain of the Galactic Union, and Arthur became a regular Captain. 
Following the creation of The Great Human Imperium, Kaiser further honoured Steele by making him the First Imperial Governor of Buran, the so-called 'Jewel of the Imperium'. After several years of service, Harrison Steele resigned his commission and retired for unknown reasons. 
He has not been seen since.
