The peaceful facade of the Cullen household is completely shattered when Lucifer uncovers a dark, horrifying secret—Edward Cullen has been physically and emotionally abusing Alice in secret, taking out his frustrations on the gentle pixie. Confronted by Lucifer's absolute authority, Edward is forced under a powerful, inescapable compulsion to confess his heinous crimes, triggering a primal, ancient rage within the Daughter of God. Lucifer delivers a devastating, bone-shattering punch that launches Edward through the house window and deep into the surrounding forest, initiating a brutal, one-sided battle. Despite Edward's attempts to utilize his vampire speed, Lucifer effortlessly uses her Kinetic Energy Absorption and Adoptive Muscle Memory to counter his every move, systematically dismantling his combat style. In a desperate, final bid to save himself, Edward bites Lucifer's arm, hoping to subject her to the excruciating three-day transformation of a Twilight vampire. However, this foolish action triggers Lucifer's Species Adaptation, allowing her to effortlessly integrate the traits of Twilight, Underworld, Charmed, and Blade vampires in mere minutes. Reborn as an evolutionary apex predator, Lucifer retaliates by castrating Edward with molecular acceleration and subjecting him to agonizing mental hallucinations and physical torment. The remaining Cullens arrive just in time to stop Lucifer from tearing Edward's head off, pleading for his life so they can decide his punishment as a family. Lucifer agrees but places a terrifying, permanent compulsion on Edward, ensuring he experiences excruciating pain and horrific hallucinations whenever he thinks negatively of Alice. With Edward thoroughly defeated and castrated, Alice moves out of the Cullen home and into Lucifer's cabin, cementing their fated mate bond. But as the dark forces of the supernatural world begin to shift, Lucifer prepares to take her mate to the ancient halls of Volterra to settle accounts with the Volturi once and for all, leaving the world of Twilight forever altered as a new shadow looms over the horizon.

The confrontation in the ancient, stone-carved throne room of Volterra marks the absolute, uncontested subjugation of the vampire government by the Daughter of God. Edward Cullen, desperate to escape his ongoing torment, attempts to expose the existence of vampires to the human world, forcing Lucifer to intervene. She easily corners the cowardly vampire, but her actions draw the immediate attention of the Volturi kings, who demand an explanation for her presence. Lucifer willingly surrenders her hand to Aro, allowing him to attempt to read her memories, only for his telepathic powers to shatter uselessly against her impenetrable mental shields. In return, Lucifer uses her own advanced psionic capabilities to effortlessly copy every single unique gift within the Volturi ranks, including Jane's pain illusion and Alec's sensory deprivation. When Jane attempts to subject Lucifer to her signature pain curse, Lucifer reverses the effect, forcing the sadistic guard to scream in absolute agony. Revealing her true, terrifying identity as the Daughter of God and the Lord of Hell, Lucifer strikes absolute, primal terror into the hearts of the three vampire kings, forcing them to sign a treaty guaranteeing the safety of the Cullens and Bella Swan. With the treaty secured, Lucifer turns her attention to Edward, subjecting him to the ultimate penance illusion before brutally crushing his skull and burning his remains to ashes. Having thoroughly dismantled the canon of the Twilight universe, Lucifer returns to Forks, graduates high school, and marries Alice in a beautiful, private ceremony. As a wedding gift, God Himself grants them two mysterious vials, transforming Alice into a light fairy and granting Lucifer the bloodlines of the Noblesse Nobles and Hellsing vampires. Armed with cosmic power, Lucifer and Alice prepare to activate their world-traveling ability, stepping through a golden portal of pure energy into a completely new and magical universe, leaving their old lives behind as they prepare to face the unknown wonders of the wizarding world.

Arriving in the quiet, suburban neighborhood of Privet Drive, Lucifer and Alice immediately sense the rich, metallic tang of blood, leading them to a dying, severely abused young girl named Rose Potter. In this alternate universe, James and Lily Potter are alive but have abandoned their eldest daughter to the abusive Dursleys in favor of her arrogant brother, Charlus, the supposed boy-who-lived. Lucifer saves the young girl's life by feeding her a drop of her immortal blood, instantly healing her wounds and initiating a deep, familial bond. After subjecting the abusive Dursleys to a powerful compulsion that forces them to confess their crimes to the police, Lucifer and Alice officially adopt Rose, welcoming her into their family. To secure their future, Lucifer takes Rose to Gringotts for an inheritance test, triggering an absolute shockwave throughout the goblin nation. The test reveals that Rose is the rightful heir to the houses of Slytherin, Gryffindor, and Black, while Lucifer is revealed as the Lord of Morningstar, Pendragon, Slytherin, Ravenclaw, Gryffindor, Hufflepuff, Solomon, Peverell, Le Fay, and Wyllt. This unprecedented revelation brings King Ragnarok himself to his knees, as he pledges the goblin nation's absolute loyalty to the newly crowned magical royalty. Lucifer claims her lordships, causing dozens of ancient family rings to fuse into her Morningstar ring, granting her immense mental defenses and magical power. She also uncovers a hidden message from her father, granting her a unique wand capable of absorbing other wands to stack their power. Armed with her new lordships and immense wealth, Lucifer secures a position as the History of Magic professor at Hogwarts, while Alice acts as her assistant, setting the stage for a massive, inevitable confrontation with the neglectful Potter family and the manipulative headmaster who still foolishly believes he can control the fate of the wizarding world.

The culmination of Lucifer's time in the wizarding world is marked by a profound, tearful act of familial love and a massive, world-shaking ascension into true, cosmic godhood. Wishing to permanently sever all remaining ties to her biological parents, Rose asks Lucifer to blood-adopt her, a request that Lucifer and Alice happily accept. Utilizing a divine ritual provided by her father, Lucifer and Alice combine their blood, transforming Rose into an incredibly powerful Archangel-Vampire-Witch Tribrid, complete with glowing wings and enhanced magical capabilities. Soon after, Lucifer begins a massive, planetary hunt for the bloodlines of magical creatures, absorbing the essences of phoenixes, basilisks, giants, and every dragon species in existence, transforming into the True Dragon King. She then locates the ancient, hidden vaults of the Greek, Egyptian, and Norse pantheons, using the Caduceus as a key to unlock their divine inheritances. Downing the glowing, golden blood of the fallen gods, Lucifer undergoes a brutal, three-hour planetary assimilation that shakes the very foundations of the Earth, multiplying her magical power and physical strength to cosmic levels. She emerges as a True God, claiming thousands of suns and moons across the galaxy to fuel her divine domains of Sky, Time, and Magic. Before leaving the universe, Lucifer confronts James and Lily Potter after they attempt to forcefully reclaim Rose, declaring a devastating blood feud that strips the neglectful parents of their magic and leaves them as functional squibs. With Voldemort's horcruxes absorbed and the wizarding world thoroughly blessed, Lucifer, Alice, Rose, and Jasper Hale activate their world-traveling ability, stepping through a golden, radiant portal into the magical realm of Alfea, ready to conquer the next universe and establish their family as the ultimate power in the multiverse. As they enter this new realm, they are greeted by the majestic towers of Alfea College, where new allies, enemies, and fated encounters await their arrival.
