From Destinypedia, the Destiny wiki
The Infinite Simulacrum was a device built by Brother Vance using Simulation Seeds and Vex architecture under the guidance of lore written by Osiris. He used the Infinite Simulacrum to create a small pocket version of the Infinite Forest to assist in his studies of the mysterious tones emitted by The Lighthouses of Mercury in response to the deaths of a Guardian. Unfortunately, the device also connected Vance closer to the Darkness and affected his sanity. Vance later used the device to open the sealed gateway to the Infinite Forest after refusing to evacuate Mercury following the arrival of the Black Fleet.
