Written by Paul Wade-Williams and running to 128 pages, Avalon contains a potted history of Somerset - including both mundane and Mythos elements - a travel guide of sorts, a selection of notable characters, and three complete, stand-alone scenarios.
- "Blood and Water"
- "Strange Little Girl"
- "St. Swithun's Hole"
Avalon: The County of Somerset was published in 2010 by third-party content provider Cubicle 7 Entertainment as part of their hugely popular Cthulhu Britannica series. Released in both print and digital PDF versions, it is currently out of print.
