The Talisman is a magical sphere that holds the power of all worlds in it. It has the ability to heal people from illness and injuries, as well as allowing the travel between all possible worlds. The Talisman itself is similar to the Maerlyn's Rainbow. However, while Maerlyn's rainbow is evil in nature, the Talisman is good.
