Geohacking is a colloquialism that refers to the practice of altering the environment of an already habitable planet. Geohacking is different from terraforming in that it is done upon planets and moons that already have established atmospheres and environments. It can also refer to modifications done on a smaller scale, and primarily to alter a world’s weather system. The Xi’an Empire utilizes the planets of the Th.us’ūng system for its ongoing research into geohacking and terraforming technologies.
