From publisher blurb: "The planet Arret exists in the same space as Earth, but in a negatively-charged dimension on a newly-discovered Slip Vector called Marlowe, after its discoverer Dr. Benjamin Marlowe. Arret is a place where not only subatomic charges but evolution itself has gone a totally different direction than it did on Earth: it is a hot, dry and desertfilled place, almost entirely bathed in red. The dunes are stalked by alien carnivores and the skies are watched by gigantic octopus-bats. Within this hostile terrain, the DayTrippers will soon discover – or be discovered by – some of the planet’s bizarre species." CRYSTAL CRISIS is a DayTrippers adventure module from the GOLDEN AGE ADVENTURES anthology. If you have that book, you don't need this one. DayTrippers uses a descriptive scale which can easily be converted to other game systems. Conversions are included for 2-12, 1-20, PbtA and percentage-based systems.
