Between the Skies: Collected Edition Hardcover

Between the Skies is a cosmic fantasy game of travel and exploration across endless worlds. It is also a set of system-neutral, modular procedures, tables and methods that can help spark your imagination in any game of weird fantasy adventure. 
It emphasizes a fluid, fiction-first approach to role-playing based on shared judgment, without reference to a single, static set of rules. It also provides all you need to generate strange and wonderful characters to venture forth into equally strange and wonderful worlds.
