From Halopedia, the Halo wiki
When the Covenant colonised the Agni system, they settled the world of Zhoist due to the presence of Forerunner cities - the Ten Cities of Edification. By 2526 they had built extensive infrastructure in the Zhoist-Rudara planetary system, constructing the orbital Ring of Mighty Abundance around Zhoist and many space stations keeping orbit in the Lagrange points of the two celestial bodies.
