From publisher blurb: This is an adventure written Cepheus Engine. The travelers are offered a job with a substantial payday, The only problem is that the job is on a burned out radioactive world in the Sonora sector of space, An alien species, long dead and gone, once used robotic walkers to invade the planet Ceqal IV. The Olonsean Empire would like to have artifacts from these walkers. The patron, however, has other ideas.
