The Ghost Talisman

The Ghost Talisman is a collection of objects that were obviously very important to someone once... but now it's in the hands of Willow, who has never seen anything like it. The talisman has the power to cast spells, its screen lighting up, strange graphics on the display, and strangely affecting the nearby area. It also has the power to transform you into something much, much stranger, the more you dabble with its magic.
