111 Tauri system

111 Tauri System is a planetary system around the star 111 Tauri, located 47.8 light years from Earth.

It is, or at least has been, the site of a UNSC colony world, Victoria. In 2531, there were major rebel activities in the system, notably at Camp New Hope. It is unclear if it is currently under UNSC control, or if it has been overthrown by rebel actions, or destroyed by Covenant activity.

Due to intense engagements with the Covenant, certain sectors in this system were depleted of UNSC munitions. This prompted the United Rebel Front to begin trading munitions with the UNSC in exchange for experienced medics to treat rebels affected by Boren's Syndrome.
