The Book of Gaub 

The Book of Gaub is an anthology of creepy magic and micro-fiction, fit for all game systems and tailored to retro/old school D&D in the style of Wonder & Wickedness. Written by seven authors, their concerted effort fleshes out the Seven Fingers of the Hand of Gaub, manifest through the filigrees of cobwebs and nails, false memories, and nightmares you want to forget
