The One Ring, also known as the Ruling Ring, the Master Ring, the Ring of Power, and Isildur's Bane, was one of the most powerful artifacts ever created, and by far the most dangerous. It was crafted by the Dark Lord Sauron in the factories of Orodruin. Sauron's intent was to enhance his own power and exercise control over the other Corporations. In this way, Sauron hoped to gain lordship over the entire E-thernet.

In here we can see GollumX contemplating the artifact after he killed his own brother over it.
