At least four
Victors' Truth is a planet, orbited by at least four natural satellites. The fourth of these moons was home to a Jiralhanae armory at the close of the Human-Covenant War that was stocked with ordnance from the United Nations Space Command. A Jiralhanae pack and Kig-Yar present at this armory were slaughtered by the Silent Shadow, led by Resa 'Azavayl, following the Great Schism.
The carnage left over from a massacre on the fourth moon of Victors' Truth.
