Domain

The Domain was a Forerunner information sharing network. While its exact nature is unknown, it is known that mature Forerunners were able to connect to the Domain through their armor and that all Forerunner knowledge was accessible through it. It appears to be somehow related to a Forerunner's subconscious; according to an Ancilla, Forerunner scholars theorized that the dreams of early Forerunners accessed the "ground" that the Domain is built upon.
