From the introduction: The Keep is an old stone tower located in the hills a few miles from Talrinel, in a wilderness area where few people go. It was built by a spell-casting member of the aristocracy, but fell into ruin long ago—legend has it, after the lord of the castle went into an unexplained rage and murdered his entire household. It is now said to be haunted. User summary: For 2nd - 3rd level characters.
