Tilt

About
Tilt was a young woman, presumably living in the Republic of Lancelot, when she was raped by a married man, causing her to become an Outlaw herself under the rules of Mother Eve's blessing. As she had not become an Outlaw of her own free will, knights (presumably knights of Lancelot) took her away to resettle in the hidden Outlaw colony in the ruins of Arthur. This led her sister, Tio, to become a volunteer at the colony, but her support was not enough. Tilt never seemed to recover from her trauma, and one day fled the colony in hopes of finding a Happiness Flower from the Kingdom of Eden. She was killed by monsters on the road.

Unfortunately for the rest of the world, Tilt's spirit did not leave the mortal plane for the journey to Camelot and resurrection. She began to manifest a dungeon of mist that became known as the Mist Labyrinth. The knights of Eden kept the Labyrinth at bay for a time by bribing Tilt with Happiness Flowers, but this was only a stalling measure. The labyrinth was only fully dissolved when Tio heard about the ghost and went to join her sister. Tilt's undead powers and heartlessness might have killed her sister, if not for the timely arrival of Aster and his family.

Aster and Tio were able to calm Tilt, and the two were married, but Tilt continued to haunt Aster to assure her sister was kept safe. Tilt and Aster even began a sexual relationship using Tio's body as an intermediary.

Personality and Appearance
Titl's personality in life can only be inferred from Tio's second-hand account, but it would seem she had an infectious smile and happy personality prior to her assault. After the assault, she fell into a depression, which seems only to have worsened under the chill of death, and the evil spirits drawn to her power. Tilt gradually became murderous, and it took Tio's recovery to convince her otherwise.

While the sisters' relationship has improved somewhat since Tio's marriage, Tilt still shows poor respect for her sister's consent in various matters, like a more extreme version of Tio's protectiveness for her and her new family.

Tilt seems to be accomanied by several ghostly forms, though it is not known if these are distinct spirits or some other manifestation of her spiritual power.

Abilities
Tilt is the most powerful ghost encountered in the World of Eve (with the possible exception of King Arthur), having created the Fog Labyrinth and drawn the attention of several supernaturally-themed monsters through unconscious power alone. Consciously applied, her powers include supernatural empathy, the ability to possess the living, the power to call and direct evil spirits.

Trivia

 * Tilt's assault at the hands of a married man is the only example of an obscure, third rule of Mother Eve's blessing that bans sex with Outlaws under any condition. The man would have become an Outlaw for the assault, and this would have caused Tilt to become an Outlaw immediately after. This rule is only explicitly mentioned in one other place, during the scene when Aster has sex with Colpis while under the influence of the Hanny Curse.
