Ages ago, before the sinking of Lemuria, the continent was populated by normal air-breathing humans, as well as the race called the Deviants. At this time, the alchemist named Atra created the Serpent Crown, a receptacle for the mystical power of Set. As Atra and the Deviant emperor Phraug fought over the Crown, the alien Celestials detonated a massive weapon, sinking Lemuria beneath the waves. The Celestials caused the skeletons of Atra and Phraug to be preserved, with both gripping the Serpent Crown as a warning against the perils of lusting for power.

The Lemurians discovered the Crown and its skeletal owners when they settled the sunken continent, but they avoided the evil remains. Naga, however, was told by Set to take the Crown for himself. Arriving at the site, Naga ordered one of his cronies to pry the Crown from the bony hands of the skeletons. When he did so, the lackey dropped dead. Undaunted, Naga took the Crown and placed it on his head, thereby gaining tremendous powers.

Set was so pleased with his student that he revealed to Naga a way to treat the Serpent Crown with certain fish oils, which preserved Naga’s youth for as long as he wore the Crown. Thereafter, Naga lived for centuries in the prime of health and vitality. However, wearing the Crown enhanced Naga’s reptilian features—his skin grew scaly, his outer ears fell away, and his skull became more serpent-like in shape. The influence of the Crown even mutated the entire Lemurian race, making their skins scaly as well.

Over the following centuries, Naga ruled as a diabolical tyrant. With the powers of the Serpent Crown, he crushed most rebellions with ease. However, a group of young Lemurians with telepathic powers were the exception. They formed a dissident movement, and eventually were able to steal the Serpent Crown while Naga slept. The rebels fled. Using a serum that enabled them to breathe air, they founded a small city within an Antarctic cavern. The Lemurian dissidents became known as the Ancients.

Lacking the Crown, Naga began to age. Fearful of his approaching doom, the despotic emperor formed a group of warriors called the Questors to recover the Crown, but for decades they failed.

Eventually, the Questor Karthon took the Serpent Crown from Prince Namor of Atlantis, the Sub-Mariner. Karthon brought both of them to his master in Lemuria. Naga mistakenly believed the Crown would restore his youth, but it did not. However, he once again possessed its other powers. In a show of might, Naga used the Crown to destroy all of the Questors except the terrified Karthon. The mad emperor then battled Namor in the arena before all of the Lemurians. Naga used the Crown to open a great chasm in the ocean floor and mentally commanded Namor to hurtle himself into it.

As the end seemed near for the Sub-Mariner, Naga was struck down from behind by the sword-wielding Karthon. Previously, to break Namor’s spirit, Naga had slain Karthon’s sister and used his powers of illusion to disguise her corpse as the body of Namor’s beloved, the Lady Dorma. After learning the true identity of the corpse, Karthon was so enraged that he murdered his emperor, and saved Namor’s life.

The Sub-Mariner had the fallen Serpent Crown placed upon Naga’s corpse, so it could ensnare only the mind of a dead man. As a result of the chasm’s creation, tremors triggered an underwater earthquake that swallowed Naga and the Serpent Crown.

Recently, Ghaur, head of the priesthood of the Deviants, and Llyra, the Empress of Lemuria, formed an alliance and reconstructed the Serpent Crown in an immense new version. They planned to sacrifice the seven “Brides of Set”— Andromeda, Dagger, the Invisible Woman, Marvel Girl, the Scarlet Witch, She-Hulk, and Storm—to empower the giant Serpent Crown and bring Set physically to Earth. However, as Ghaur mentally probed deeply into the Crown, he unintentionally released the spirit of Naga, who claimed the power of the Crown as his own. Naga and Ghaur fought a battle of wills, and finally they and Llyra suddenly vanished. Freed of mental domination, the Brides of Set hurled the Crown into an immense sea cavern, where it remains today.
