"They call it ‘Haidon’, which apparently means ‘Home’. We’re taking that home away."

Haidon, designated PX8-448 by the Tau'ri, is a planet in the Milky Way galaxy.


Haidon was a Xi'an colony planet that had been liberated from the System Lords.

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 Duizhu Cheung 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")
