This artefact is spoken of in whispers by the nighted cults of the Hyborian age. It is rumored to be a window into all of space and time - but with the cost that the user risks baring their soul to powers from the outer dark.

The Serpentmen of Valusia were in possession of this object, and how they came to be living beneath the volcano in the Exiled Lands is a mystery. Perhaps fleeing their genocide at the hands of the legendary Kull of Atlantis, they made their way to the Exiled Lands where they befriended the Giant-kings through worship of their deity, Set. In return they were allowed to live in the Caldera of the volcano and build their cities there.

It was, however, too late for the serpent men, a degenerate and dying race, lacking the genetic diversity to continue. They found themselves coupling with snakes and lesser reptiles in the hope of preserving their species but as time passed, they lost all hope of survival and instead, preyed for bitter revenge upon the races.

They crafted a staff with their ancient magics and summoned a presence via the trapezohedron, to inhabit the staff and lead the Giant-kings to their downfall.

If they must die, they would take as many with them as possible and most especially, the cursed children of humankind.
