Clanbronwyn Hotel is a location from Trilby's Notes. A cursed hotel on Clanbronwyn Island, it is the primary location of the game. Having been build on top of the stump that was once the tree that contains the soul of Cabadath, the borders between the World of Technology and World of Magick is especially thin within and in the area surrounding the hotel causing it to be very popular place for Cabadath to manifest.

A version of the hotel also exists in the World of Magick, but it is build by Chzo, who does not seem to completely understand the purpose of the building, and it is therefore a very crude and twisted interpretation of the original.
