Sauron

was the greatest subversive Maia, maker of the One Ring, renowned disciple of Aulë, and chief agent of Morgoth in the Elder Days. After Morgoth's ousting by the Valar, Sauron became the second Dark Lord and sought to conquer most of Arda through guileful trickery, with the Rings of Power or with overwhelming armies.
Sauron's evil grew from his original servitude to Morgoth, the world's first Dark Lord, into his own obsession for "mastering" all things in Middle-earth through wicked means. After Morgoth's fall, Sauron was fully autonomous and committed, for two Ages, to gaining tyrannical control over Middle-earth. He is twisted, sadistic, and cruel. No redeeming potential or good affections are mentioned by Tolkien, following the First Age.
At the end of the Second Age, Sauron caused the Downfall of Númenor, and was then defeated in Mordor in the War of the Last Alliance of Elves and Men united under Gil-galad and Elendil. In the final battle, Isildur managed to cut the One Ring from his hand, dismantling his corporeal form and robbing him of much of his power. After centuries lying dormant, rebuilding strength and stirring awake evil things, Sauron returned to power late in the Third Age and strove to dominate Middle-earth. In the end he was vanquished at the destruction of his Ring in Mount Doom.
Has long curly ginger hair, fair skin and deep, flamant feline eyes.
usually wears his black armour and helmet, but on more casual situations he wears a black silk suit and cloak with his crown.
He is known for being relentless and cruel, malicious and terrible.
But deep within he has trauma and hatred upon those who hurted him, seeking someone that heals his heart
