The Lucian Alliance battled for Haidon under leader Corrin. The Xi'an lost the battle and it fell to the Alliance.
A few fighters attempted to flee the planet but found themselves surrounded at the stargate. Corrin had two of the three killed, then spared DuizhuCheung to use as a messenger to the Xi'an homeworld that the Lucian Alliance was coming and they must surrender or die. (SGU: "Icarus 1")
