Gary Gygax's Cosmos Builder
A fantasy worldbuilding toolkit for creating cosmologies, planes of existence, dimensions, and the strange worlds between them. It presents common planar elements alongside guidance for blending or adapting them to form original settings. Ready-to-assemble components help users develop and share a cosmology for campaigns across different game systems, with tools that can be used independently or combined into a larger structure.
