“The Nevernever is a big place. In fact, it’s the biggest place. The Nevernever is what the wizards call the entirety of the realm of spirit. It isn’t a physical place, with geography and weather patterns and so on. It’s a shadow world, a magical realm, and its substance is as mutable as thought. It has a lot of names, like the Other Side and the Next World, and it contains within it just about any kind of spirit realm you can imagine, somewhere.
