A mysterious limbo realm in C.S. Lewis' The Magician's Nephew, one of The Chronicles of Narnia. The Wood between the Worlds is an endless forest where nothing happens and no animal lives (except for an old guinea pig once transported there). Among the trees are many pools of water just a couple of inches deep. When wearing the proper magic rings, a person can travel from world to world by emerging from and descending into the pools. When a world dies, as Charn did, its pool dries up. Professor Digory Kirke and Polly Plummer discovered the land of Narnia when they were children by visiting the Wood.
