Reciprocal Hyperdrive: The portal drive functions by opening up a gateway into hyperspace, the gate swallows up the starship instantly, the gate is actually a wormhole connecting from 1% of the speed of light to 100 times the speed of light, it takes 3.5 days of acceleration with a 1-g maneuver drive to reach 1% of the speed of light. If one does nothing while in hyperspace, it takes 11.899 days to cross 1 parsec, 23.798 days to cross 2 parsecs and so forth. The thing is, its easier to go faster than slower, if you accelerate in the direction of travel at 1-g for another 3.5 days, you go at infinite velocity, which takes you out of the Universe, if you stop short of that say you accelerate at 1-g for 1.75 days, you reach 200 times the speed of light, which means you can travel 2 parsecs in 11.899 days, if you accelerate for another 0.875 days after that, you reach 400 times the speed of light and can travel 4 parsecs in 11.899 days, accelerate at 1-g for another 0.4375 days after that and you reach 800 times the speed of light, and you can travel 8 parsecs in 11.899 days. As a game rule, I'd stop it there, though theoretically you could just keep on going. You could travel backwards in time, but first you must reach infinite velocity an then go faster to do that, the problem is, you'd cover an infinite distance the moment you reached infinite velocity and you'd end up in another Universe. People who've gone all the way to infinite velocity have never returned, no one knows what happened to them. In any case beyond 800 times the speed of light navigation becomes difficult, gravity fields affect the path of FTL ships to a greater extent the faster they go, you get to a point where even a small gravity field, such as that produced by a rogue planet or even an asteroid, can throw the starship way off course, you also can't see where your going while in hyperspace, so you don't know if you are off course or not until you drop out of it, and that can only be done after slowing down to 100 times the speed of light.
