Sauron was initially called Mairon, he was a Maia in the service of Aulë, as was Saruman. He was well versed in the art of magic and blacksmithing and had great ability in this field. Mairon followed Melkor in his quest to rule the earth and became his most terrible lieutenant. He will be at the origin of the death of Finrod Felagund and as Annatar, Lord of the gifts, he will forge the rings of powers with the help of Celebrimbor who did not listen to the advice of distrust of Galadriel and Gil- Galad about Annatar, which will cost him his life. Great was the influence of Sauron over men thanks to these rings of power and disproportionate was the greed of the Dwarves and their love for all the riches that the mountains brood. But the Elves were wary of this gift and only used their rings to preserve their people, their lands. When the One Ring was cut from Sauron's finger, Isildur did not have the heart to destroy it and keep it for himself but it cost him his life and the ring disappeared. It will be centuries before the ring falls into Frodo's hands and he destroys it in Mount Doom, thus definitively eradicating Sauron's spirit.
