How to Custom Make a Ghost From Scratch

This is a terribly interesting development that we're thinking of trying to replicate in the Black Mansion as soon as we settle on just what sort of ghostie we'd like to have. A group of people got together and decided to make up a ghost and see if that ghost would subsequently arrive. They came up with a name, a back story and even did some drawings. Then they began visualizing their ghost, eventually holding seances. It wasn't long before they were getting responses from the ghost in the form of rapping on the table and answering questions by rapping once for 'yes' and twice for 'no.'

We're thinking we'd like a nice ghost rather than one that likes to show up looking like a screaming skeleton like the one pictured here. Maybe a nun.
