Vex

The Vex are time-traveling robots who are hostile to the Guardians. Located on Venus, their fortress is known as the Citadel. The Vex also have a presence on Mars.

Overview
Their heads are cone-shaped, with a red photoreceptor at the center. They arrive in the solar system via warp gates, likely from another time in the past or future. Their robotic bodies still carry a hint of organic components (particularly their mind cores, which contain a milky radiolarian fluid), and individual bodies might be humanoid, creature-shaped, or in-between, but often with long, vicious clawed fingers. The seemingly illogical geometric designs of their structures come together like giant ant hills. Headshots do not do much damage, but shooting their abdomen power cores causes them to explode.

The Vex appear to be mass-produced units, constructed of an unknown metal alloy resembling hammered brass. All attempts by Guardians to communicate with them failed. It is said that Vex encryption is unbreakable.

Humanity had known about the Vex as early as the Golden Age, when the Ishtar Collective discovered their ruins on Venus, as well as captured a live specimen. Interestingly, according to Ishtar Collective records, Vex are capable of generating simulations of real-world events with perfect fidelity and predictive ability - essentially running a parallel reality in their minds which is arguably indistinguishable from the "real" universe. To Collective researchers, this ability raised profound philosophical quandaries about the nature of reality. Eventually the researchers were driven near to the point of madness when they discovered the Vex had simulations of themselves and perfectly predicted their every action, as they started to wonder if they themselves were just Vex simulations, so they decided to bring in a Warmind to intervene on their behalf.

The Vex are at war with the Cabal, waging a guerrilla war in the deserts of Mars. The reason for this apparent invasion is that they are surging to protect the Black Garden, their birthplace, which the Vex are being summoned to for an unknown purpose. Guardians who manage to break into the Black Garden discover that the Vex in fact worship the Black Heart, an abomination that lends power to the Vex.
