From publisher blurb: Tiny worm-like vermin lurk among the power conduits and access panels of the Muinmos system, feeding on stored data and threatening to wipe entire databases. Meanwhile, down on the surface of Muinmos 4, strange ooze-like beings dream of the far corners of the universe, their sleeping minds a window onto the Ethereal Plane. 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.
