A type of travel invented by the Precursors in which their ships use a directed field of dark energy to enter a network called the “Slip Stream”. The Slip Stream is a network of dark energy tunnels that run inside the fabric of the space-time continuum at a quantum level. These networks were supposedly created by the Precursors by an unknown method.
Slip Space travel lets one travel between galaxies with remarkable ease, and to the Alliance’s knowledge is untraceable.
Ships that have tried to follow others into Slip Space Tunnels without a Slip Space Drive have been atomized.
Long range slip space travel like that between galaxies requires a tethering point, a specific device that grounds the traveling ship in this universe, without that tethering point that ship could be lost in the space between universes, adrift in the space-time continuum.
