The eye, forged from the very core of Naxxramas's forges. Enchanted by the Kel'thazad himself with great powers and unimaginable attributes. The object was placed in the care of a lone assassin, whos name is unknown to most. Because of his magical eye, however, people only refer to him as Goldeye.
Goldeye was intrusted with if because he is hard to see, let alone catch. His skills with blades are near unmatched, as well as his uses of toxins and other horrible potions. He also is able to sneak out of any battle without a trace, making killing him all the more hard.
This item does not truly exist in World of Warcraft. It is an exclusive item invented by the mind of Demongo55.
