Atlantis

Uncle Andrew described Atlantis as "a great city with palaces and temples and learned men" to Digory when Polly vanished out of our world into the Wood Between the Worlds. The Atlantean Box which his 'fairy'god mother; Mrs. Lefay, had given him contained magic dust that had been brought from another world just when our world was only just beginning. From this dust, Uncle Andrew succeaded in making the Magic Rings, which could take people from various worlds to the Wood between the Worlds and back again. This implies that the Atlanteans themselves may have been capable of travel to different worlds. It thus may have been that Atlantis forged links between our world and others, such as that mentioned in the claim by Mrs. Beaver that Jadis, a native of Charn, was descended from Adam's first wife Lilith, an inhabitant of Earth.
