Sol System

The Solar System is the planetary system inhabited by humanity. During the Golden Age, humanity forged an empire that spanned much of the system, but the catastrophic effects of the Collapse forced humans to retreat to Earth, abandoning their many worlds to various other forces.

Notable celestial bodies

 * Mercury—a former garden world, now converted by the Vex into a planet-sized machine.
 * Venus—a volcanic jungle world and the site of the Ishtar Academy, humanity's greatest center of learning. Now occupied by the Vex and the Fallen House of Winter.
 * Earth—mankind's homeworld. The only safe human settlement is The Last City, with pockets of hidden human communities. The Fallen House of Devils and House of Kings control the rest of the planet.
 * The Moon—Earth's only natural satellite. Once the site of a small colony for supplying the rest of the system, now the location of the Hive's stronghold, with a minor House of Exile presence.
 * Mars—the first human city outside of Earth, Freehold, was founded here. Now occupied by the Cabal, who are fighting invading Vex forces for control.
 * The Black Garden—a Vex realm accessible from and tied to Mars.
 * Phobos—one of Mars's two moons. Phobos was controlled my the Cabal until the Taken invaded and destroyed the Cabal outpost.
