Rock of Eternity

The Rock of Eternity is not so much a rock as it is a mystical underground cavern that exists in between dimensions. It is the base of operations of the ancient wizard known as Shazam and it is where he had imprisoned the Seven Deadly Enemies of Man. Supposedly, the Rock of Eternity was constructed from two large rock formations that originated in both Heaven and Hell. Shazam desired a champion in the modern age to continue the fight for justice. Utilizing a mystical subway system, he brought a young boy named Billy Batson to the Rock of Eternity and bestowed upon him the power of six elder beings.
