It all begins with Marley's Ghost appearing on a door knob tag. This is followed by visits from the Ghosts of Christmas Past, Christmas Present, and Christmas Yet to Come. Chilling, spooky, and yet Christmassy! It's probably more light-hearted than you guys are used to in a séance, especially if you are a Krampus fan, but it has some features you might find interesting: magicnook.com/WizJ28/wizj28-04ChristmasSeance.htm
This one seems to work. Sorry about the one above, but you could always head for The Magic Nook and locate Wizards' Journal 28, item #4 which is entitled "Christmas Seance." Not that hard to figure out.
