The Ghost of Mordor. (Demon Slayer x LOTR)

Backstory and Bio

After the destruction of the One Ring, when Sauron was left without a physical body and stuck as a shadow of his former self, he was surprised that the Fellowship did destroy the Ring. Most people wouldn't even think of doing such a thing, greed getting the better of them, and it made Sauron to rethink everything he'd done. Unlike what happened in the early 2nd age where he feigned repentance, this time it was real. He saw what he did was against of his true desire of true order, and asked for forgiveness from Eru Iluvatar. The Great Creator along with a Maia heard Sauron's voice, and made a deal: that Sauron can work his way back to being an angel and truly repented, Eru will grant him a physical form after the Maia pleaded to him. Eagerly, Sauron agreed and worked as a Maia for hundreds of thousands of years. He saw what he was blinded to which was peace and balance. He kept his old moniker the same to show he can change how people view him. Along the way, he met many different types of beings: the Great Ones which used to be called The Nameless Things, with forms and voices that would make most human minds insane, and whom exist in multiple dimensions; to the the Architects, who had an interesting solution of immortality, which involved infusing themselves with technology. This solution inspired Sauron with his later works in his never ending life.
After the next few millennium, a portion of humans that studied magic, a lesser Maia, who ate hundreds of the newer Maiar, and some other lesser Maiar turned their backs on Eru. They claimed that they were "Gods" while some of them called them, particularly the ones born a mix of Maia and human called the "Isu" or precursors ruled the world by creating and enslaving humans. In response to this, Eru sent Sauron to aid the humans to freedom and punish the Isu. Sauron started a rebellion by manipulating events to happen like the 1st Isu hybrids( Adam and Eve)to escape with an Apple and the accession of another hybrid named Kratos. Along the way, he met a being called the Morrigan, known as the Goddess of Death and War in Celtic mythology. Sauron had a love interest with her after the death of her husband, Dagda from Sauron's hand. Sauron created 20 rings of power that instead of enslaving the wearers like the ones for the Nazgul, these empowered and wizened them. Alongside the rings Sauron made a couple of artifacts called: Bûrz Hont which worked like the ones from his time, but he can gain control over the Apples of the Izu to Sauron in secret. It allowed knowledge to flow through the person holding it and Sauron can directly communicate to them. This was useful for when the Izu started storing their consciousness in vaults or in certain Pieces of Eden. Sauron gave the artifacts to leaders of the Human rebellion which gave the humans a high chance of winning the war. Sauron staged many events ending the pantheons from the inside like making a prophecy of Odin's death to make Odin to avoid it which was futile or have the creation of Pandora's Box to be made to make the Greeks "Gods," fear it and allow Kratos to open it. During the final battle between the humans and the Izu, Sauron's physical form was destroyed after a battle that lasted a week but took out hundreds of thousands of foes during that time. When Sauron "died" a solar flare and earthquake happened causing the ground to split across Earth and wiped out most of the Izu race along with the humans since Eru was sad that his creations might lose, so he caused the disasters to start the world over again. After the fall of the Isu fall, Sauron took on a human form and walked the Earth living as a Gladiator in the Roman Empire from the 3rd century to High ranking knight in France in the 12th century.
