Sapphire of Agartha

The Sapphire of Agartha was the Men from within the Earth's most revered and holy artifacts. It was stolen by undercover FBI Agent Nicholson who had been secretly planted in the underground civilization of Agartha.

It's power potential was unknown.

The Sapphire of Agartha was destroyed by Agent Cooper in July 1955.

An Ancient Relic
According to Zerrath, the Sapphire of Agartha had been around over 10,000 years earlier, when their race had ruled the planet from Atlantis. Then it was known as the Sapphire of Power, and the Sapphire of Agartha is only a fragment of the original size of the relic.

The ancient, powerful ruler of the Atlantis civilization, Zalanubar, had been experimenting with the Sapphire of Power in an attempt to weaponize it against intruders from another civilization based around the binary star system Zeta Reticuli.

However, Zalanubar's attempts backfired and caused a worldly calamity, which resulted in the sinking of the Atlantis continent and the survivors fleeing to underground sanctuaries that eventually became the civilization of Agartha.

Theft
Sometime in late 1954, the Sapphire of Agartha was stolen from it's shrine in the Underworld by undercover FBI Agent Nicholson, who brought it to the surface via a tunnel in the Superstition Mountains, Arizona USA. After fighting off his Agarthan pursuer Zellor, Nicholson left it for Operative-132 of the Above Top Secret Project AGARTHA to pick up.

The MacGuffin
Operative-132 recovered the Sapphire of Agartha, and, along with his partner FBI Agent Cooper, intended to move the object to a secure facility in upstate New York as requested by Science Division head Dr. Edward Teller.

However, O-132 encountered problems along the way, and "hid the Sapphire in a safe spot". The mystery of this 'safe spot' became a focus of the US Government as well as the Agarthans thereafter.

Discovery and Destruction
The Sapphire of Agartha was re-discovered by FBI Agent Cooper and NSA Operative-1138 in July 1955 in the Forest near the Blue Ridge Mountains, where nearby encounters had previously occurred.

It was later stolen from Agent Cooper by his wife Kate, who gave it to Zerrath, although it ultimately came into possession by Agent Cooper, who smashed it against the cement sidewalk, causing a massive energy release that knocked out power to several miles worth of the nearby grid.

Somehow, Agent Cooper, Zella, and Zerrath, who were all nearest to the impact point, all survived the destruction of the Sapphire of Agartha.

The Sapphire of Agartha was a common glass paperweight with a little lighting animation added.

In Diabolical Tales: Part III, Kate even refers to it as a paperweight.
