The Hartlewick Horror
From Wikipedia, the free encyclopedia

The Hartlewick Horror is an adventure published by FASA in 1985 for The Doctor Who Role Playing Game, itself based on the long-running BBC television series Doctor Who.
The player characters, usually consisting of one or more Time Lords and their Companions, are sent to Earth in 1923 by the Celestial Intervention Agency to investigate a large energy field centred on the English village of Hartlewick, where a number of people have recently disappeared at night. The characters will eventually discover an ancient alien imprisoned underground who is using its telepathic powers to force the local villagers and an archaeologist to free it.[1]
Pregenerated characters are provided for the Fourth Doctor, and his well-known companions Leela, Sarah Jane Smith, and Harry Sullivan.
