Haidon

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

History
Haidon was a Xi'an colony planet, that at some point around 2009, had been recently 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 were coming, and they must surrender or die.
