Spica Publishing says:
A body drifts in the vacuum of space near the ruins of a habitat, dimly illuminated by the cooling corpse of a star. Strange noises echo down empty corridors. Ghostly figures appear outside spaceship windows. Voices from the past and future call for help on the radio. Ships go missing without a trace in the darkness.
Are you brave enough to explore Xibalba?
Spica Publishing presents System Book 2: Xibalba – a complete planetary system around a white dwarf star compatible with the current edition of the Traveller or any other SF RPG, designed for use in an existing campaign or as the focal point of an adventure. Inexplicable events plague the inhabitants of the system – are they really haunted by the ghosts of the dead, or is there a more rational explanation for the manifestations?
