Atlantis

"For in the very dawn of time Atlantis was already a great city with palaces and learned men."

- Andrew Ketterley

Atlantis was a mysterious mythological city on Earth that was, according to Andrew Ketterley, a real place that was the first great civilization on Earth, existing near or at the very beginning of the world.

When Polly Plummer vanished out of our world into the Wood Between the Worlds, Andrew told his alarmed nephew, Digory Kirke, the story of how he had become able to transport people to other worlds. He described how his "fairy" god mother, Mrs. Lefay (she was a human but supposedly with some fairy blood) had given him a box on her deathbed, telling him not to open it but to destroy it immediately. Knowing that it was ancient, but not from any primitive civilization he could recognize, he did some research and confirmed it to have been created in Atlantis. Opening it, he discovered magical dust that had been brought from another world when our world was only just beginning. From this dust, Andrew succeeded in making the magic rings, which could take people from various worlds to the Wood between the Worlds and back again.
