Raven Peninsula
The Raven Peninsula was a peninsula on the west coast of Scotland. A group of Sea Devils hibernated beneath the peninsula.
In 1870, Hamish Ravenscaur founded Ravenscaur School in a valley on the peninsula. (COMIC: Clara Oswald and the School of Death)
In 1903, a duo of Skithra attempted to awaken the Sea Devils below to act as army to conquer Earth for them only for the Tenth and Thirteenth Doctors to thwart their plan. (COMIC: Alternating Current)
In 1909, the peninsula was separated from the main land by a cataclysmic earthquake which woke up the Sea Devils. Raven Peninsula became known as Raven's Isle. (COMIC: Clara Oswald and the School of Death)
