Peveril Castle

There are reports of a phantom monk, a white knight standing near the ramparts, a ghostly horse and dog, and the "ethereal" sounds of a lady singing.

Update 27/9/21: The Facebook team responded to my request for recent events; "Sadly I am unable to verify such claims for you. We are a relatively new team and no past reports have ever been passed on to us."
