A Warp-Vortex allows the warpee (owner) plus sub-warpee (passenger) to move from one place to another in a trilli-second. Warp-Vortexes are typically backpack-mounted. Pocket versions do exist but are quite expensive. Each Warp-Vortex has its own password, which the users will not share under any circumstances (so don’t even ask).
When doing a round-trip, the warpee uses the Input Nozzle to get there, and the Output Nozzle to return. Full Combat Extrication entails deploying the Warp-Vortex during actual combat.
