Bilehurst Cragg was a village in Lancashire, close to Pendle Hill. Its name, "Bilehurst", meant "sacred tree on a hill".
The village was abandoned, and in time, forgotten, following the escape of the Morax from their prison within the hill and the Thirteenth Doctor's intervention. King James swore to erase all records of the village while Ryan Sinclair asked that he, at least, ensured that the villagers all got out all right first. (TV: The Witchfinders)
