Soell system

Soell is the star that Threshold, Basis and Installation 04 orbit.

The star's location in the galaxy is unknown. Prior to Halo's release, some speculated and theorized that it was factually the star Iota Horologii (50 light-years from Earth ), based on lateral hints from Bungie that that star was connected to the game somehow (specifically a sign left in front of the Bungie Webcam).

Behind the scenes

 * Although an excerpt in the 2003 Halo Sybex Guide is the first canon source to refer to the star as "Soell", the name was originally proposed by a fan, Loren Petrich.
 * The star's name is generally believed to be a reference to former Bungie Community Guy Matt Soell.
