[Creative Exercise] Worlds in a word, planes in a paragraph

[Bohandas]

The Macrocosm- Planetary system where each planet corresponds to one of earth's continents. Possibly Africa, Eurpoe, and Asia are all moons of a single gas giant, and north and south america are a double-planet system. The PCs are anthropomorphic animals (rats probably work best; stowing away in the greys' spaceships, going between planets) with a red-in-tooth-and-claw society like the one in the webcomic Kevin and Kell. Everything in the setting is overshadowed by the setting's equivalent of humans - grey alien type creatures with an interplanetary civilization (verging on becoming interstellar), frightening levels of individual intellignece, a language too complicated for anyone else to speak, cat and dog servitor races that worship them as gods (and who will try to sacrifice the PCs to them if the PCs are rats as recommended), and a cthulhu-like disregard for the other creatures of the system.

And also the entire system is covered in Roadside Picnic-esque nonsense
