Hyperspace

The Collector entered into a state of consciousness that was simply that: consciousness. Consciousness in its barest, purest form: the psionic profile. In this state, the Collector could perceive in even greater detail the psionic tethers that swirled within the dimensional waters.

If there had to be an equivalent to conventional ocular systems, then the Collector would have described the experience as being in the center of a whirlpool of rippling, shining rainbow currents, and lining those currents were psionic tethers: bright white, root-like protrusions that floated up, breaching the surface of the waters and connecting to the material world.

This space where the Collector's psionic profile inhabited independent of its physical body was called a Simulacra.

A lesser point in hyperspace meant for creating lower range warp gates.
