The Unyielding Ravenclaw of Birmingham by sunkissedtrampolin3

CURRENTLY BEING REWRITTEN. She's a Shelby. Trouble runs in her blood. Dragged from Birmingham to Hogwarts, Larissa Shelby carries more than her family's notorious name-she carries ancient magic the wizarding world thought was long buried. But Hogwarts is not all as it seems. Curses whisper through the shadows, relics hunger for blood, and every choice drags her closer to the edge. Enter Sebastian Sallow: clever, infuriating, impossible to ignore. He's as reckless as she is sharp-tongued, and together with Ominis Gaunt, they're pulled into a spiral of secrets Hogwarts was never meant to reveal. As Larissa flirts with power-and danger-she has to ask herself: is she carving her own path, or stepping into the darkness her family was born to rule? Because at Hogwarts, survival isn't about following the rules. It's about rewriting them. Trigger Warnings: Dark and mature themes Sexual content (characters aged 18+) Graphic descriptions of death Violence and physical harm

for the hope of it all // Sebastian Sallow x reader by incendio22

''You seriously need to stop calling me your friend,'' Sebastian tells me in a low voice. ''Then what should I call you?'' I ask curiously. My stomach is fluttering like never before. ''I haven't quite figured it out just yet. But 'friend' is not it.'' He says as he squeezes my hand harder. ---- Sebastian Sallow x reader, a love story. When the summer between Y/n's 5th and 6th year at Hogwarts, she cannot stop thinking about Sebastian Sallow, despite the horrible things he did last year. She knows that what happened should have been the end of their relationship, but for some reason she does not consider it to be over. In fact, Y/n is unsure of her feelings towards him. Something about him just makes her feel like home. During their 6th year their relationship develops further, while facing new obstacles. One night Y/n discovers something that could mean the end of the wizarding world that requires help of Sebastian as well as Ominis. This is a story about love, friendship, betrayal and sacrifices. ---- Note: This takes place after the end of the game Hogwarts Legacy, but uses characters from the game.

The Secrets || Sebastian Sallow POV fanfic by misspurrple

The world thinks I'm the arrogant one. The rule-breaker. The charming duelist who gets away with everything. They're not wrong. But no one knows what's at stake when I look at Anne. No one knows what I've done. What I'll still do. I made a promise. One I intend to keep. Not for the Headmaster. Not for the school. Not even for the girl with the violet eyes and the clever mouth who's stumbled straight into my path. Qynna Veilinharv. She wasn't here before. Now she's exactly where I need her. She casts spells like she's never learned them, argues like a Slytherin, blushes like a Hufflepuff, and hides things like the world depends on it. I should have left her alone. I didn't. She keeps walking straight into my plans, and every time she does, it becomes easier to let her. The closer she gets, the more I can see what she's made of. And the truth is, some part of me likes watching her try. Even if she never realises how deep she's wandered. Even if, by the time she does, it's already too late. Includes: ✨ Secrets, lies, and very bad decisions ✨ A meddling, mysterious girl with more power than she knows ✨ A cocky protagonist who absolutely has a fan club ✨ A slow descent into dark magic Sebastian Sallow x Fem!OC (but replace "Qynna" and "Veilinharv" with your own OC if you wish- we're all secretly shifting anyway.) ⚠️ Trigger Warnings This story includes themes of grief, terminal illness, death, PTSD, anxiety, depression, obsession, self-harm, light intimacy, violence, blood, dark magic, alcoholism, and emotional ruin. Spoilers for Hogwarts Legacy throughout. Game scenes may appear with new context, expanded dialogue, or darker consequences. Leave comments, theories, chaos, pain. I read them all like they're letters from Azkaban. Thank you for being here. And good luck. You'll need it. - misspurrple

The Heartbreak Prince Sebastian Sallow by Destinychild27

It's been a year since I finally defeated Ranrok. I thought I would have everything I ever wanted after the fight was over. But the problem was instead of winning, I lost everything. Sebastian distanced himself from me, Ominis started to stray away, people started to look at me differently. All I want is for Sebastian to notice me and know my secret, know my goals, know me for me. No matter what happens there is only one thing true that nobody will know except for me for now, is that I am completely and utterly in love with him. SPOILER WARNING: Will contain major spoilers from the Hogwarts Legacy game. Will contain mature and explicit scenes, including with violence, romance, mentions of abuse, torture and death. Please read at your own risk! I do not own anything Hogwarts Legacy, Wizarding World or by Warner brothers. All rights to them..... my characters/ story are owned by me.
