System Book 2: Xibalba
A complete planetary system for Traveller and other science-fiction roleplaying games, set around a cooling white dwarf and the ruins of a former habitat. Ships vanish, strange sounds echo through abandoned corridors, and apparitions and impossible radio messages unsettle the system’s inhabitants. The setting can be added to an existing campaign or used as the focus of an investigation into whether the manifestations are supernatural or have a rational cause.
