the x-series is set more than 750 years after these events. a single terraformer craft appears in the solar system using an apparently experimental gateless jumpdrive. the terrans reverse engineer the device. in its maiden flight, the x-shuttle, piloted by test pilot kyle brennan, is accidentally transported into the x universe. unlike before, this part of the network is inhabited by several space faring alien races and the descendants of nathan r. gunne's fleet. the terraformers are attempting to get to earth and kyle must stop them.
