Eye of the World
A huge crater in Northern Canada, its history ancient and mysterious, is known as the Eye of the World. The Eskimos in that area say that it is older than mankind. A magic wielder who is at Adept level of mastery or higher can go there and immediately feel its eldritch, evil magic everywhere. It is the last access to the dimension known as the Realm of the Beasts. So many mystical wards and seals guard the dimensional aperture that no one can penetrate them without using the Great Key. The proper incantations must accompany the use of the Great Key for it to open the aperture.
