I finally picked up Richard Pett's Your Whispering Homunculus, published by Kobold Press when I was at The Dragon's Lair for Pathfinder Society Organized Play last week. Man, this book is a thing of twisted beauty. Reading through its imaginative jottings, many of which inspire guffaws, others extended flights of fancy, and some, occasionally, retching, I thought of how it could enrich your game planning or could be used on the fly to generate elements for your game. GMs should definitely check this out.
It made me think of another fun book of tables, with which it pictured above.
