"No life stirs here. Not anymore."
Grimoire description[2]

Mercury is the first planet in the Solar System and the closest to the Sun. It is a Vex Machine World.


Following its transformation into a garden world by the Traveler, the planet was inhabited by humanity during the Golden Age. [3] At this time, the planet was covered in grasslands and trees with pink leaves. During the Collapse, the Vex undid this transformation [4] and completely changed Mercury into a Machine World within days of their arrival. [5] Dendron, Root Mind arrived in a massive Vex construct to begin seeding the planet with Vex architecture and poisoning all life with Radiolarian fluid. Eventually the Infinite Forest was created to serve as the Vex’ simulation farm, with Panoptes, Infinite Mind at its heart. The Sun itself, as seen on the planet's surface, appears to be massive in size yet not blindingly bright—a possible result of Vex engineering.[6]

Though much of Mercury is dominated by the Vex, others have managed to visit the planet, including the Cult of Osiris who maintains a camp there in the form of The Lighthouse. Flawless champions of the Trials of Osiris are permitted to visit the Lighthouse where they can find stores of Glimmer and other treasures, although the only rewards available are the ones in the chest at the edge.[6] The Sunbreakers have their Forge here as well and the Cabal built an outpost at Vertigo, but have since mysteriously disappeared.[7]

During the Red War, Mercury was partially fragmented to fuel the Red Legion's superweapon, The Almighty. Seemingly half of its mass now exists independently of the rest of the planet.[8]

After Dominus Ghaul's death, the Vex began to gather on the planet. Osiris discovered that Panoptes had simulated a future where the Vex would achieve total victory in the solar system and wipe out all other life. Vex from the past and future were converging on this timeline to carry out their plan, but were foiled by the Guardian.



  • With the release of Curse of Osiris, Mercury possess the smallest public location in Destiny 2, smaller than even Titan.
    • However, it is the most complex of the maps with the Infinite Gate leading to the Infinite Forest that makes it appear larger, much like Titan, and the Moon of Destiny.
