Mercury

"No life stirs here. Not anymore."

- Grimoire description

Mercury is the first planet in the Solar System and the closest to the Sun.

Overview
Following its transformation into a garden world by the Traveler the planet was inhabited by humanity during the Golden Age. During the Collapse, the Vex undid this transformation and completely changed Mercury into a Machine World within days of their arrival. 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.

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. The Sunbreakers have their Forge here as well and the Cabal built an outpost at Vertigo, but have since mysteriously disappeared.

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.

After Dominus Ghaul's death, the Vex began to gather on the planet.
