Chi Ceti system

Summary
The Chi Ceti system was a system located in the far reaches of UNSC space. It was home to the planet Chi Ceti IV. In 2525, the Battle of Chi Ceti was fought here between the UNSC Commonwealth and a Covenant frigate. In this battle, the Covenant ship was destroyed, though Samuel-034 died in the process. The facility on Chi Ceti IV was evacuated shortly thereafter. It is unknown whether this planet was glassed by the Covenant or not, but it is unlikely due to the fact that the planet had no major human population centers. It is likely that the system is completely vacant and Neutral currently.
