Rock of Eternity

The Rock of Eternity was the lair of the wizard Shazam. After his death, Captain Marvel became its guardian. The Seven Deadly Sins were imprisoned here.

Some time around 5,000 years ago, the Champion created the Rock of Eternity from two large rock formations — one from Heaven and one from Hell — to hold the "Three Faces of Evil", a dragon-like demon, captive.

The Rock of Eternity is a nexus of power in a nearby realm of existence that channels power to anyone utilizing the power of the wizard Shazam. It is a way station of power. As the Guardian of the Rock of Eternity, Marvel is now one with the Rock as it is apart of him. He channels the energies of the primal God-wave and the Greek Lords of Magic through the Rock of Eternity.[citation needed] As such he is infused with the duty to keep the power and the magic of the earth realm in balance. As keeper of the Rock of Eternity he also holds the dark forces at bay.
