Specifically the Caturday, anthropomorphic cat people, and not just all the rules and cultural background you need to play them. No, Catopia Prime also brings you an entire system to explore from its star Kåtze to the outermost orbit of Pachés. The focus of the system is Catopia Prime, homeworld of the Caturday and center of their expanding hold on the region. Venture into the Kåtze system to discover:
- The hot humid jungles of Sh'lo where the wealthy travel to vacation in tropical splendor or risk their lives hunting the planet's many deadly lifeforms.
- Explore the barren planet of Scraw'b and the exiled necromancer Fluafie the Apostate that lurks with her army of the undead, plotting the overthrow of the Caturday and eventually the entire known universe.
- Catopia Prime, a planet rich in history and resources. From the capital of Catopia City to the ruins of the Lost's Lands there is adventure aplenty for the brave or foolish.
- Plus three other planets, ships of the Caturday, a pantheon of gods, and new technology, there is something in Catopia Prime for every player and GM!
