Every universe potentially has its own Supreme Grimoire containing the spells which define its reality and the magic which you can perform within that reality. In this Octavo we have assembled scattered secrets for a Supreme Grimoire for Roundworld, the universe in which you're standing. To this end we have taken some inspiration from Pratchett's Discworld, and a lot from Theoretical Physics and Practical Chaos Magic.
