Goronu

The Goronu is an ancient magical artifact capable of raising the dead as Stalfos or ReDeads. Much like the Eye of Truth and Malmord, it appears as a small sphere, made of an unknown silver metal and bearing the image of a skeletal jaw. When used, it releases an unholy green light.

Age of Myth
During the Age of Myth, the great Kovalian Empire rises under the protection of the First Sage of Spirit Kovaloo. With her guidance and their powers, they invent the art of necromancy. The artifacts used to aid with this magic were the mysterious Goronu.

Ancient Age
After the Kovalians had collapsed and left a barren wasteland in their place, all of their powerful objects were lost to the sands.

Gerudo Wars
The Sheikah wizard Agahnim comes into the possession of one of the lost Goronu. He entrusts it on Ganondorf and the Gerudo prior to their planned invasion of Hyrule. The desert king utilizes its power over undeath during the attack on Nal Ordona to resurrect dead Gerudo and Hylians in the middle of the battle.

After the skirmish, Ganondorf and his consort Nabooru agree to not use the artifact any longer, as it proved to be too unstable. The undead that would rise would make no distinction between friend and foe. It's heavily guarded in Gerudo territory.

Return of Sulkaris
After the Gerudo Wars, Lord Akazoo would pay the Robber Baron Halthor of the Keaton Cartel to steal the Goronu from the Gerudo. That way he'd use it to survive Sulkaris' coming rampage and ammass an undead army.
