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: Combat Evolved's release, it was speculated that Soell is actually the star Iota Horologii, which is roughly fifty-five lightyears from Earth, based on hints from Bungie that the star was connected to the game somehow, specifically a sign left in front of the Bungie Webcam.

Trivia
The system is named in reference to Matt Soell, a former Bungie employee.
