From publisher blurb: “No other ancient city on Mars had been laid out in that manner; and the strange, many-terraced buttresses of the thick walls, like the stairways of forgotten Anakim, were peculiar to the prehistoric race that had built Yoh-Vombis.” From the Face on Mars to Precursor artifacts orbiting dead quasars, the mysteries of space aren’t all astrophysical. For some answers, you have to dig. Ruins — of cities, starships, and planets — hold danger and horror, riches and knowledge. What a lost species or a cunning GM can build, bold exo-archaeologists and their players can uncover.
