The Gatekeeper's Crystal was a powerful magical device, which, according to legend, had been created by a powerful lich. The truth, however, is that it originated from the Outlands, having been carried by a mysterious being called the Gatekeeper, whose sole duty was apparently to guard a crossroads of gates across the planes and spheres, preventing anyone who wished to restrict access to it from blocking the travel of others. It was stolen (with the assistance of a deity, it was said) by Iyraclea, a lich and ice-priestess of Auril of the Great Glacier known as the Ice Queen, as part of her attempt to conquer Myth Ondath.
