Warp Relativistic Antimatter Propulsion
Warp Relativistic Antimatter Propulsion (WRAP) is the highest-tier method of interstellar propulsion and allows spacecraft to travel faster than light by utilising a grid control system to alter universal constants as the vehicle moves. Due to the second maxim of exophysics, this only decreases the time required to travel to the destination, not the energy consumption; and, as such, truly ludicrous quantities of antimatter are necessary in such a system. In human society, the use and availability of WRAP technology is extremely limited, in part because of the ludicrous expense to operate it and in another due to the classification of grid control as a Class Z restricted weapon, of which may only be possessed by Raven. Due to this, all ships outfitted with WRAP are required to station Raven security personnel on their crews.
Because assuming grid control over a manifold requires the manifolds to be distorted, the starting procedure for a WRAP drive involves the external irradiation of the entire craft, while it is empty, with entropic radiation produced by a cavity reactor; this also means a vehicle might be stranded in deep space if grid control is lost part-way through a journey, as the system cannot be restarted during flight. The extreme hazards from such a field and the dire consequences if an accident were to occur mandates that any such craft be launched free from all personnel except those strictly required for the mission. Launching WRAP spacecraft is completely prohibited within a 5-LY radius of the Solar System.
