From publisher blurb:
Star System Sets offer new planets to explore, dangers to overcome, lifeforms to study, and cultures to document. Modular enough for any campaign, each double-sided card presents a complete ruleset for ease of reference, allowing GMs to fill in the blank spots on their star charts.
Card types include Race, Planet, Character Options, Equipment, Monsters, and Mini-Adventure. Each set is available à la carte or as a six-card bundle.
The jungle planet of Mien is home to danger, mystery, and some of the galaxy's finest starship foundries. Monsters prowl the jungle floors while silver cities seems to float among the canopy. And all across the wildlands, the sound of finely tuned engines roaring into the sky echoes over an alien landscape. For the locals consider it a sacred duty to explore the galaxy, questing endlessley after their lost goddess, Maltur.
