Hidden deep beneath the jungles of Venus, the Vault of Glass is an ancient Vex stronghold that exists outside the normal flow of time. Within its massive stone and metal halls, the Vex experiment with reality itself, erasing intruders from history and rewriting outcomes to suit their designs. As Guardians descend into the Vault, they face powerful Vex defenses, cryptic mechanisms, and trials that demand perfect coordination and awareness. Past, present, and future blur together as fireteams fight to disrupt the Vex’s control and prevent them from shaping the fate of the universe. At the heart of the Vault waits Atheon, Time’s Conflux, a being that commands time itself and stands as the final barrier between the Vex and absolute dominance.
