Consisting of a single scenario written by Stuart Boon, The Ballad of Bass Rock contains material which was originally intended to be in Cubicle 7 Entertainment's Shadows Over Scotland book, but was cut due to space issues. It runs to a total of 14 pages including the front cover and is part of Cubicle 7's popular Cthulhu Britannica line.
The plot involves a group of investigators being trapped on the Bass Rock in the Firth of Forth, Scotland, with a hungry shoggoth. The book contains all of the necessary handouts and information on a small number of NPCs.
The Ballad of Bass Rock was published by Cubicle 7 Entertainment in 2012 as an ebook-only release, but is no longer available to purchase.
