Infinite Forest

"An infinity of possible worlds, so perfectly simulated as to be indistinguishable from the experiences I once called “reality.” I can touch them, taste them, pass lifetimes in them! They grow within this machine like fruit upon a tree — no, a forest of trees, its fractal expansion nigh unmeasurable. (...) What an awful, destructive machine this is. I must know everything about it."

- Osiris

The Infinite Forest is a location accessible through a gateway in the Fields of Glass, Mercury. It is a virtual simulation of the universe which the Vex created to plan their actions in reality. The Vex hollowed out Mercury's core and in its place built the mechanism that generates the Forest. It was overseen by Panoptes, Infinite Mind until its destruction. Simulated versions of Dendron, Root Mind created by Osiris have attempted to take control of the Forest, but have been destroyed by The Guardian before they could assume the role.

Overview
The initial area of the Infinite Forest, the interior of Mercury's core, contains four tower-like structures with gateways, three of which lead to different time periods within the simulation, and one that leads back to Mercury's surface. The sleek, futuristic tower to the left of the entrance leads to the distant past where Mercury is a lush jungle; the tower directly across the entrance, which is comprised of conventional Vex architecture, leads to iterations of the present; and the crumbling, darkened tower to the right of the entrance leads to the far future, where the Sun is long dead and the Vex have spread everywhere. As Guardians move toward the main towers, they encounter simulated Cabal, Fallen, and Hive, as well as Vex, and must defeat the disguised units called "Daemons" to generate new pathways and advance. The one enemy race that does not appear in simulations are the Taken.

Within the actual simulations of the past, present, and future, Guardians will continue to encounter simulated enemies from the other races. For example, in one of the infinite variations of reality being analyzed, the far future where the Vex have triumphed over everything may also contain Fallen survivors.

History
The construction of the Infinite Forest began during the Golden Age, while Mercury was still a garden world and the Vex had only recently arrived. The algorithm used to generate the Forest was housed within the Gardener's Spire, overseen by Dendron, Root Mind. Panoptes, Infinite Mind was tasked with managing and interpreting the Infinite Forest's simulations to inform the Vex's strategies in the "real" universe.
