An ancient, dark magic has spread through the Scottish highlands, and into the doors of Hogwarts. Her name is Eden Whittaker and what she thought was supposed to be a normal entrance into the seventh year at Hogwarts School of Witchcraft and Wizardry was anything but. Now, Eden experiences her first taste of adulthood as she manages friends, relationships, and a deadly secret that is eating her alive, and if she doesn't master it soon, will destroy the people and places she's come to love.
This book is for ages 18+ and contains sexual content and violence. All characters involved in sexual content are 18 years of age or older, and in their seventh year at Hogwarts. This story contains spoilers for the game Hogwarts Legacy and will contain a lot of story lore from the game as well. This book will start similar to the way the Hogwarts Legacy game started, with our character aware of their unique ancient magic abilities but for the moment is encouraged to keep it hidden. My goal with this fan fiction is lots of character development and romance with the MC and our favorite men at Hogwarts. Enjoy!

A Flame in the Ruins || Sebastian Sallow
~ a Hogwarts Legacy fanfic ~ SPOILER WARNING: Will contain major spoilers from the Hogwarts Legacy game. I do not own anything Hogwarts Legacy, Wizarding World or by Warner brothers. All rights to them..... my characters/ story are owned by me. Scenes and occasional quotes taken from the game but I added my own additions. In her seventh year at Hogwarts School of Witchcraft and Wizardry, Scarlet Blanchet, a brilliant and determined student, uncovers a startling truth-she possesses the ability to wield Ancient Magic, a long-forgotten and immensely powerful force. Her discovery coincides with a time of great upheaval: Ranrok, a vengeful goblin leader, has ignited a revolution against the wizarding world, seeking to control the very magic that flows through her veins. As the chaos of war brews, Scarlet embarks on a perilous journey to understand her gift and stop Ranrok's destructive ambitions. Along the way, she crosses paths with Sebastian Sallow, a fellow seventh-year known for his charm, secrets, and his maverick approach to magic. What begins as a wary alliance soon evolves into something deeper-a growing bond forged through shared danger, hard choices, and the shadows of the past. Amid the darkness rising around them, a new tension begins to bloom. As their feelings for each other intensify, so do the stakes. The line between right and wrong blurs, and both must decide how far they're willing to go to protect one another-and what sacrifices they're willing to make. Will contain mature and explicit scenes, including with violence, romance, mentions of abuse, torture and death.

**MATURE THEMES/SMUT** Picking up the pieces of a mess you didn't make is never a great experience. Walking into your seventh year, with an undeniable crush on your best friend, you knew it would be an experience you wouldn't forget. With Renee (MC) working to heal Sebastian, you find yourself desperately trying to mend Ominis along the way. Though taller and broader, Ominis is trapped in his trauma, especially as he struggles to find where to go after Hogwarts. Family, Friendship, Love, and Lies lead us into the tale of Whenever, Wherever.

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.

For the entirety of your sixth year, Sebastian was at Azkaban. While Ominis understood that it was a necessary action to take considering what Sebastian did, he didn't forget that you encouraged it, or that you partook in the dark arts yourself. It was against everything he stood for. He warned you every step of the way, and neither you nor Sebastian listened to his warnings. By a stroke of luck, the ministry has decided to give Sebastian a second chance. He gets to come back to Hogwarts for his seventh year of schooling. Ominis is still Sebastian's friend, but he wants to keep you away from him at all costs. He hates you for what you did to his best friend. On a happy note, St. Mungos finally found a cure for Anne Sallow's curse, and she's back at Hogwarts for her seventh year as well. Your friendship with her blossoms, and makes it even harder for Ominis to stay away from you. Even though he hates you, he can't deny the attraction between the two of you. Everything changed one night at a party in the Slytherin common room when you two come in close contact. But can he fight his feelings and stay away from you? ---------- TRIGGER WARNINGS: Sexual Content: 5/10 Mental Illnesses: 7/10 Violence: 3/10 Self Harm: 6/10Complete
