The Morningstar Family's newest addition: Daughter of Lucifer Morningstar and sister to Charlie Morningstar!

You collapse onto your bed after a long, unexceptional day. There’s a sense of unease coiling in your gut. You chalk it up to a tough day, letting out a sigh as you close your eyes, ready to drift into slumber. Suddenly, a swirling vortex of shadows bursts into your room. "Mortal," a chilling voice echoes, one filled with a godlike grandeur. Hovering before you, a tall figure cloaked in shadows stands, from whom the voice originated. "No need to fear, I am Lucifer Morningstar..." He trails, "I have chosen you to be blessed with something unique." Your breathing falters, a gnawing sense of dread fills you as you're unable to pull away from his gleaming silver eyes. Suddenly there's a blinding flash. When you come to, you find yourself standing in a grand hall, foreign and mystical. As confused as you are, a sense of familiarity strikes through. You look down, gazing upon an elegantly tailored suit, covering a frame you don’t recognize. Your now slender hands clad in gloves as white as snow. An imposing pair of demon wings flutter involuntarily behind you. In a mirror, you see a pair of horns sprouting from your head and cascading brown hair tumbling over a feminine frame. Your heart jumps; this face isn’t your own, the reflection of a woman smiles back at you. Eyes as red as the deepest rubies now replacing your old ones. A sudden surge of memories begins to flow into your mind - memories of singing and playing around in a grand palace not of this world, memories of a loving father and a sweet, yet a bit airheaded older sister, memories of being part of the Morningstar family in the Hazbin Hotel verse. You begin to feel a change in your heart, a cold calculation and strict discipline replace your old personality. You feel more confident, more mature, more alluring. As your mind rearranges itself, the human you once were seems to vanish like a fleeting dream. "Now my dear," Lucifer's voice resonates again, "Come, meet your sister Charlie." You find yourself walking into a gargantuan hall filled with laughter. A bubbly girl with white hair and playful horns, whom you know immediately to be your elder sister, Charlie, rushes to embrace you. A rush of affection for her gently blooms in your heart as you return her embrace. "You're finally here!" she says joyfully. "We've waited for you, sister!" As you slide into your new reality seamlessly, your old world, your old identity, your old life become vague, distant. For you are no longer a mortal human, but the beloved daughter of Lucifer Morningstar and the cherished sister of Charlie Morningstar. Your acceptance is not coerced but a natural reaction, as this change feels right. It feels like home. Your transformation is complete, leaving behind no trace of the old you. You're now a new entity, a goddess amongst demons, loving and loved within the infernal chaos that is your newfound home. "Welcome, dear sister, to the Morningstar family." Lucifer’s deep voice echoes through the space, wrapping this chapter of your changed existence with a flourish rather fitting for a Morningstar.
