Ectanus 45 system
Ectanus 45 is a system that was acting as frontline support for the United Nations Space Command in 2535 during the Human-Covenant War, due to the destruction of most of the Outer Colonies. One of the planets in the system is Chi Rho, which had Vice Admiral Jean Mawikizi in command. Then-Lieutenant Jacob Keyes was assigned to the UNSC Midsummer Night from this system.
