In 2535, human insurrectionists had created a colony within an asteroid field in the 23 Librae system after the destruction of the colony Madrigal by the Covenant years earlier. Spartan-II Gray Team was sent in covertly to seek out and destroy any data pertaining to the location of inner colony worlds, per the Cole Protocol. At the same time, the Covenant had discovered the secret colony and proceeded to try and steal coordinates of human colonies and destroy the colony in 23 Librae. Though the Covenant was successful in destroying the colony, Gray Team successfully managed to destroy the data, and with the help of Jacob Keyes, rescued most of the population of the colony prior to its destruction.
