You'll need your own rule set and dice for Dungeons & Dragons, Pathfinder, or a compatible game to play.
Some poets make teaching guides for their books of poetry. I make short scenarios for role-playing games.
You don't need to have read my book BARROW to play this one, although I do appreciate it. I'm now at work for the scenario for my upcoming book of poetry, DEMONSTRA, coming out through IFP in April 2013 with a cover by Vongduane Manivong! :)
And apparently I just created the Lovecraftian Great Old One Gopnyai, Devourer of Moons.
