Author's blurb: Prepare to get lost in a world of your own imagination, steered only slightly by the rules within this book. This is a solo role-playing game, a game you can play by yourself. Write your characters journal as they explore the strange lands of Colostle, a castle so colossal that fields, valleys, mountains, and even oceans rest within its ‘rooms’. Discover 3 incredible character classes and a simple ruleset that only requires pen and paper and a deck of playing cards, to embark on a grand adventure. Play it alone with the rules in this book, or use the world of Colostle and the classes as the setting for your next multiplayer RPG adventure. But although the rooms of the Colostle are inviting, beware the Rooks, strange lumbering stone automatons that patrol and guard the world’s mysteries. What will you discover as you venture deep, into the Colostle?
