Charon Base was a remote deep space research complex established by the Z.C.T. Corporation and run by Professor Ernst Kleist. Located within a remote asteroid, it was the main facility for Z.C.T.'s advanced Xenomorph research, and in particular the company's top-secret Project Chimera. As such, it was the site where Kleist created the Rogue. The complex was destroyed following a disastrous Xenomorph outbreak that claimed the lives of most of its inhabitants.
