After the Jiralhanae were assimilated into the Covenant around in 2492, Jondum became host to a number of orbital refineries intended to convert the planet's gases into fuel. Nearly a century later when the Covenant fragmented, several Jiralhanae chieftains and their packs battled one another for ownership of these refineries. As a result of the fighting, only a fraction of the original platforms remained capable of operation as of 2560.
