Kilroy is the name of an Earth-like planet first settled by colonists from the United Republic of Earth in 701 N.E. It had virtually no native sentient lifeforms, though subsequently some members of variant human races, Keiki, Arvi, Horseheads, and Rikiari did settle on the same world along with "normal" humans. It later on was to be captured by and ruled by the Mantis Lords until the time of Jumpweb of the New Universe. As a newly independent planet, Kilroy was governed by remnants of the Mantis Lords and surviving elements of the Krypteia secret police, though the traditional racism of the Mantis Lords was officially abandoned, and the Solar Church of the Unconquered Sun was legalized after being outlawed for centuries under Mantis Lord rule.
