This System Reference Document (SRD) describes a framework for playing TTRPGs. It is primarily based on Cairn but draws inspiration from a variety of other games as well, described in the Bibliography.

The SRD describes the framework. The rest of the pages and sub-pages are for more specific games and genres with rules that would support those styles of play.

A separate section is pending for referee rules for running a game.

SRD version 0.3.1. Basic Rules.

Heretics, expansion for fantasy role-playing games.

Eridanos Star System, expansion for space horror role-playing games.
