Andrew Dorian was a Basiliskan mercenary and Solarian admiral.
Andrew Dorian was born in 4266 on Basilisk. His father, Benjamin Dorian, was the leader of the Dark Star Company, Basilisk's most successful mercenary companies. From an early age, Andrew was trained to be a mercenary general by his father. Training was brutal and long but by the time Andrew was 27, he was a successful commander in his own right.
In 4293, Benjamin Dorian was killed in battle, leaving the leadership of Dark Star to Andrew. Dorian's first assignment after becoming Khan was to put down a revolt on the Solarian world of Gilgamesh IV.
