Eridanus system

The Eridanus System is a UNSC system in the Outer Colonies where the Eridanus Rebels based their revolution.

History
The rebels, under the UNSC turncoat Colonel Robert Watts overthrew the civilian government of the system in 2494. The UNSC struck back two years later in Operation: TREBUCHET, and forced the rebels out at the cost of four destroyers. Watts was presumed killed in the attack, but in fact he escaped to Eridanus Secundus in the system's asteroid belt with the rest of the rebels

It remained a place of much hostility against the UNSC, as Dr. Catherine Halsey stated many pirates and rebels were operating from the system. The boy who would become the legendary Master Chief was conscripted here in 2517, and in 2525, a group of SPARTAN-IIs led by John-117 entered the system aboard the Destroyer UNSC Pioneer, They boarded the cargo freighter Laden and travelled to the rebel base and captured Watts.

The system's main planet, Eridanus II, was glassed by the Covenant in 2530 and the UNSC abandoned the system. However, the asteroid base survived, and the SPARTANs later returned to the system in 2552 aboard the captured Covenant flagship Ascendant Justice, fleeing from the Battle of Reach to expediate repairs at the Rebel base. However, a Coveant fleet followed and destroyed the base, with only the Ascendant Justice escaping.
