Spacial rift technology is treated as a form of Hyperspace technology. It works on the principal of wormholes.
In order to use Spacial Rift technology, the user must first have to Origin Points. One must be on the ship using the technology while the other must be at the desired location, or the desired location must be somewhere in between. The ship activates the Hyperspace core which opens a Spacial Rift between the two points, in which space is condensed far more than through basic Hyperspace technology or even Hyperdrive technology. This because the condensed space is contained within a secure boundary so there is little risk of an Implosion.
