Luz the Lilim
Monster girl encyclopedia crossover. Luz is the adopted daughter of Lilith, the demon lord, and is, for all intents and purposes, a lilim. Her backstory is that she was born of a noble father and her commoner mother Camila who was a maid in the city of Lescatie. However she doesn’t know this at first. She believes her mother is her father’s stuck up noble wife. Her father was forced to marry her though, as he truly loves Camila. Camila isn’t allowed to tell Luz that she is her real mother, but the two do interact and she serves as Luz mother figure for the first several years of her life. Luz is also discovered to be a hero with a talent in swordfighting and magic, and trains regularly. The training is hard and the order is incredibly harsh on her, but her real mother and father are always there for her. However when Luz was eight her father passed away, and after that her stepmother fired Camila. Then the Order began training Luz even harder, and would punish her if she didn’t live up to expectations with permission from her stepmother. One day she finally had enough and ran away. After some time, she stumbled across a small house in the woods. Knocking on the door, she is surprised to find Camila there. Camila takes her in and reveals the truth that she is Luz’ biological mother. They live there happily for a few years, until the order tracks her down again. They capture the both of them, and Camila is declared an ally of monster for trying to sway a hero away from their duty and is executed, while Luz is forced to watch. She is then locked away, deprived of almost all food, and her stepmother came in regularly to beat her. They intend to break her into submission so she will only follow orders, but Luz remains strong. This goes on for a few months, till Luz is nearly dead from exhaustion and starvation. Then the fall of Lescatie happens, and Druella, while invading the castle, discovers the situation. She walks in on the stepmother whipping Luz while members of the Order watch. Luz’ back is a raw mess, and her wrists have been rubbed raw by the manacles she is hanging from. Druella, seeing this, flies into a rage and kills everyone in the room except for Luz, who she then immediately takes back to Royal Makai to see her mother for emergency healing. Once they get there Luz is all but dead, and the only way to save her was for Lilith to flood her body with an enormous amount of demonic energy. This changes her into a succubus, and soon she discovers she is essentially a lilim. She is declared as such, and with the help of Lilith, her husband, their daughters, and all the other monsters in the Royal Makai Luz recovers and becomes the happy girl we know.
As a Lilim, Luz is actually similar to a Lesser Succubus in appearance, something which she is happy with as she likes her furry body. She has white hair and red eyes, but keeps her normal skin tone. She has large wings that are mostly white but the inner part of the wing membrane is lilac. Her tail is white, but it darkens to a bright fuchsia near the tip, starting at the lower third. Her horns are on the smaller side, and are the satan type on this photo: https://pics.onsizzle.com/horn-guide-i-tried-collecting-horns-which-are-likely-to-17740496.png . She has royal purple fur covering her forearms, her legs up to her thighs, her upper back and shoulders, and her front including most of her chest, though the top of her breasts are free from fur.
Luz will often explore the world disguised as a human, looking for others who were trapped in a similar situation to her to save. However, she won’t convert them into monsters unless they ask to become monsters. This is how she stumbles across the portal to the boiling isle. She is wandering through a human city when she spots a strange owl dragging a bag of trash. Recognizing that it is no ordinary owl, she follows it through the portal and meets Eda.
Titans are a race of godlike beings different from the normal gods like the chief god. They created their spirit world in order to not have to deal with the chief god, and witches and demons are the descendants of the different races and animals they brought with them. Lilith, the demon lord and not the Clawthorne, will gain the power to allow monsters to have human male babies at the end of the fic after consuming titan’s blood, which will boost her powers tenfold for a short amount of time.
Luz will bring Eda to Lilith after episode four and learning about her curse, and Lilith will use her immense power to turn Eda into a new race of monster, the Lechuza, or Owl Witch. They are of the griffon family and dark beast type. Her appearance is her harpy mode from the show.
Luz reveals that she is a Lilim during covention, shocking the isle. Eda will also reveal her status as a Lechuza.
Odalia is very abusive of Amity, and Luz will quickly recognize this. She will also recognize that Amity has the potential to become a powerful monster. The two become friends sooner than in canon. After the events of wing it like witches, Odalia will lock Amity away in a special room and leaves her without food and water. Luz finds her there with the help of the twins and frees her, taking her back to the Owl House. Amity begs to be transformed, and Luz does so, turning her into a Baphomet, though she appears her age and not that of a little girl.
Belos is a human hero who was a member of the order from the age of the former demon lords. When he realizes that Luz is capable of turning other humans and witches into these new kinds of monsters he becomes desperate to destroy both her and any other monster girl.
