This is Annulus, a system for playing tabletop RPGs. Annulus is a game about solving puzzles and overcoming problems with your friends as part of an ongoing cooperative narrative. One player is called the GM (or “referee”). You now have all the necessary context and vocabulary to understand what's going on here.

It's also in a continuous beta state, with many rules and explanations existing only incompletely on this site itself. If something is vague or contradictory, ask me what it means at the table.

The basic rules live on the character sheet.

Due to no current or planned playtesting campaign, detailed changelogs will not be kept at this time.

This is a system for playing characters and worlds that make perfect sense in context but sound like batshit gonzo heavy metal mad-libs when you describe them to somebody else.

This is a game about exploration, danger, and coming home again- and slowly being changed and effecting change of your own by the process.
