Sauron: The Lord of the Rings
Sauron, originally named [[Mairon]], was a spirit of the order of [[Maia]], associated with the smith-god [[Aulë]]. From his origins, he possessed a deep love for order and coordination, but this virtue was twisted into a hatred of all friction and dissent. This desire for control led him to become the chief lieutenant of the first Dark Lord, [[Morgoth]], during the [[First Age]].
The Deceiver and the Rings of Power
After the defeat of [[Morgoth]], Sauron hid in Middle-earth rather than face the judgment of the [[Valar]]. In the [[Second Age]], he assumed a "fair form" and took the name [[Annatar]], the Lord of Gifts. He infiltrated the Elven-smiths of [[Eregion]], teaching them the secret arts of craftsmanship.
Under his guidance, the [[Rings of Power]] were forged. However, in the fires of [[Mount Doom]], Sauron secretly forged the [[One Ring]] to rule them all. When he placed it on his finger and uttered the [[Ring Verse]], his treachery was revealed, sparking the devastating [[War of the Elves and Sauron]].
The Fall of Númenor and the Last Alliance
Sauron’s power grew until he was challenged by the might of [[Númenor]]. Realizing he could not win by force, he allowed himself to be taken prisoner. Within years, he corrupted the Númenórean King [[Ar-Pharazôn]], leading to the island’s total destruction. Though Sauron's physical body was lost in the abyss, his spirit fled back to [[Mordor]].
He was eventually defeated at the end of the [[Second Age]] by the [[Last Alliance of Elves and Men]]. On the slopes of [[Orodruin]], [[Isildur]] cut the One Ring from Sauron's hand, causing the Dark Lord to vanish from history for over two millennia.
The Necromancer and the War of the Ring
Sauron slowly reformed in the [[Third Age]], first taking the guise of [[The Necromancer]] in the fortress of [[Dol Guldur]]. After being driven out by the [[White Council]], he returned openly to [[Mordor]] and rebuilt the [[Barad-dûr]].
His search for the [[One Ring]] drove the events of the War of the Ring. He commanded vast legions of [[Orcs]], [[Trolls]], and Men from the East and South. Despite his military superiority, Sauron’s fatal flaw was his inability to imagine that anyone would seek to destroy the Ring rather than use it. When the Ring was finally cast into the fire by the intervention of [[Gollum]], Sauron’s power collapsed entirely. He was reduced to a "malicious spirit that gnaws itself in the shadows," never again able to take form or influence the world.
