Satella

Satella (サテラ) is the Witch of Envy responsible for the Great Calamity 400 years ago who is currently sealed underneath the Pleiades Watchtower. In reality, the Witch of Envy is a separate personality, born when she took in incompatible Witch Factors. Satella formally debuted in Arc 4 as a supporting character, whilst the Witch serves as an overarching antagonist throughout the series.

She possesses a yet-unexplained connection to both Subaru and Emilia, and was also the one who gave Subaru Return by Death. Throughout the series, the Witch punishes Subaru whenever he violates their "contract". Satella herself did not debut until Arc 4, where she and the other witches helped Subaru accept himself and change his views on Return by Death.

Appearance
Satella has a thin body with long silver hair and purple blue eyes. When Subaru encountered her at Echidna's tea party, she wore a black dress made of shadows that seemed to wave in accordance with her heartbeat. Initially, he was unable to see her face because of a black shadow covering her above her neck, which was created out of his reluctance to accept her, however he later accepts her and becomes able to see her face, mentioning afterward that she looked exactly the same as Emilia.

Personality
Contrary to popular belief, Satella and the Witch of Envy are separate personalities, formed when she took in incompatible Witch Factors. The two personalities tend to fight each other. Both personalities love Subaru, though the Witch of Envy personality is much more aggressive about it, while Satella is much more reasonable and cares deeply about his well-being.

History
400 years earlier, Satella absorbed Envy Witch Factors she had no compatibility with, resulting in the creation of her Witch of Envy personality. However, this alternate personality was not the reason for her subsequently going out of control and killing countless innocent people and nearly destroying the world. Despite the efforts of many, including the Dragon, the Sword Saint, and the Sage, Satella was unable to be killed and was instead sealed in a shrine that is watched over by Shaula.

Abilities
Authority of Envy (嫉妬の権能 Shitto no Ken'nō): Satella is able to use the Authority of Envy.
 * Although the abilities of the Authority of Envy haven't been revealed, in the Web Novel, Minerva mentioned during the Witches' Tea Party that Satella might direct her jealousy (妬み Netami) toward her if she stepped in between her and Subaru, suggesting that it's something that affects people remotely.

Shadow Control: Satella is able to control shadows, though it's unknown whether this is a part of her Authority of Envy. They erode or destroy all life and matter around her as well as taking abstract things like thoughts and sometimes even memories and mixing them together. It's also shown that she's capable of manipulating someone's feelings and emotions, amplifying or fabricating them to her own liking. In Arc 7, Beatrice suggests that her Shadows might have something to do with Shamac as the're able to separate a person from their mind, similarly to how Shamac works. In addition, she was the one who teleported Subaru, Rem and Louis to the Empire.


 * Garfiel_Tinzel_ep.35_5.png]] Satella is able to create shadow tendrils which she uses to capture, impale and decimate her enemies. The tendrils are strong enough to hold transformed Garfiel in the air and incapacitate him. She is also able to slip the shadows into someone's body through wounds and disperse them outwards, effectively destroying the opponent from the inside out. In some instances, she can also be seen creating hands from her shadows, gripping Subaru's heart whenever he speaks about his ability to anyone who isn't her.

Time Manipulation: Satella does have some degree of control over time, as she either manually or enabled Subaru to turn back time whenever he dies. It is unknown whether this is part of her Authority of Envy or a completely different ability.
