Castles & Canaries is a tabletop role playing game rules hack inspired by other d20 systems.
This system focuses on easy to understand and quick to teach rules, fast combat, and player creativity. It was built to take the best ideas from several systems and combine them into something that was simple and fun to play.
Any kind of adventure or story can be played using Castles & Canaries. Though this booklet generalizes towards medieval fantasy with armor, weapons, and magic, these can be easily swapped for thematic counterparts.
