The Chch'ptk were a galaxy-wide species that fought a war with the Kklxin, with whom they shared the Gehenna Galaxy. After their galaxy was destroyed, they set off towards the Crucible Galaxy in search of a new home.
Records of their original physiology were lost. While the Kklxin preserved themselves with frozen embryos on a mobile planet, the Chch'ptk opted to store themselves in data form within a virtual world aboard the starship Afterlife.
Chch'ptk are only capable of interacting with the real world through robotic avatars. However, most refuse to leave the simulator, preferring to leave the machines to maintain the Afterlife.
The Chch'ptk existed in the Gehenna Galaxy. It is also known, based on archives discovered on the Afterlife during the era of the Second Galactic Senate that their home planet went by the name of Chch'trk. The Kklxin and Ch'chptk pooled their resources to end the tyranny of Minos-Vaskus by destroying him, but in doing so rendered the Gehenna Galaxy uninhabitable.
