"The signal from Phobos is incredibly powerful. It might be a distress call. But then, we've never heard the Cabal send out a distress call before. Approach the base with caution, Guardian."

— Zavala^[1]

Phobos is one of two asteroid moons orbiting Mars. The Cabal used Phobos as a beachhead for their invasion and occupation of Mars when they arrived in the Sol System. Later, they somehow altered the asteroid moon's orbit for unknown reasons, bringing it significantly closer to the planet. A common belief among Warlocks is that Phobos was moved to its current orbit and is being held in place by the Ice Reapers and their Psion Flayers, who are only an order away from unleashing it as a weapon.^[2]

Overview[edit]

The City Vanguard believed Phobos to potentially be the command center and staging ground of the Cabal Skyburners, who were commanded by Primus Ta'aun and his lieutenants. Presumably the Skyburners were marshaling a "second fleet" with the intent of launching a full assault on the inner system.^[3] This is confirmed when The Guardian investigates a major Cabal evacuation of Fleetbase Korus at the start of the Taken War in the mission The Coming War. The Asteroid appears to have already been settled with a Cabal base, with Cabal Plows clearing out more area.

With the arrival of Oryx in the Sol System, the Taken have swarmed Phobos, overwhelming the Cabal and forcing them to evacuate a major base.^[4]^[5]

After the deaths of the Ice Reapers Psion Flayers, Phobos has noticeably begun to recede back to its natural orbit away from Mars. With Mars vanishing by the Pyramids years after, Phobos would remain orbiting derelict.
