Summary
This is what he’d been waiting for, this is why he’d suffered centuries in an odd sort of stasis. He’d seen the rise and fall of empire after empire, felt spikes in magic and heard whispers of legend that were so close to the real thing he’d nearly deluded himself into believing it time and time again, but nothing had felt quite like this. After an entire millennium of waiting, the King had returned.
Or: Harry Potter is the fated Future King of Camelot and Merlin isn't about to let him grow up in Surrey with no knowledge of magic. What results is a Harry who's much better trained and much more well equipped to dive headfirst into chaos and a Merlin who remembers what it's like to care.

Summary
A 30-year-old woman, overworked and stressed, passes out from exhaustion in front of her computer. She wakes up to find herself in an unfamiliar place, a young child with blonde hair and blue eyes instead of her old Hispanic, brown-skinned, brown-eyed self. Her mind is still her own, but her body is different, and she slowly realizes that she is inhabiting the body of young Petunia Evans, Lily Potter's older sister, in a different timeline. The world around her is unmistakably the magical world, with the familiar faces of Harry Potter, Severus Snape, and others.
As she navigates her new life, she discovers she has the ability to see fragments of the future and past—visions that seem to be both her own memories and glimpses of other timelines. Determined to fix the mistakes of her past and save the lives of those she loves, she begins to alter events and build relationships, particularly with Severus Snape. However, not everything goes as planned, and the path to redemption is filled with challenges, heartbreak, and sacrifices.

Summary
If the horcrux hunt began in 1979, right after Regulus Black discovered Voldemort’s secret, how challenging would’ve it been? Without some of the critical information Harry Potter and his friends possessed by their 7th year, how likely would’ve it been to succeed? No time-travel, no unprecedented luck, just the resources available in the late-70s/early-80s.

When Sirius’ brother comes to him with information that could potentially change the course of the war, the couple’s thrown into action while forced to reckon with the fact that neither side entirely trusts them. -

Summary
Lady Enora Dominique Rosier had been born for one purpose and one purpose only: to secure the heritage of the Noble House of Rosier. Born into privilege and power, in a society that required nothing less than duty and sacrifice to keep it. Two paths to glory laid before her: first, a marriage to the House of Black. Or second, nothing short of entering the Harem of the Emperor himself, the only other choice that would prevent her godfather from being offended on his grandson and House's behalf if she refused him.
Protocol said that it was the Emperor's Choice that mattered.
Rose begged to differ.
An Imperial Harem A/U, bridging the Riddle and Marauder Eras, focusing on Harem Politics and a dash of romance and smut.
Let the games begin.

Summary
The year is 2050 and the world has gone to hell. Harry Potter is MIA. His wife and children died in an explosion. A new Dark Lord has almost complete control of the UK. In a stroke of desperation, a plan is made to save everyone and everything. Hermione Granger has found someone to train and to send back. She only hopes it works,
It is a Time Travel theme with elements of mystery, love and unprepared issues, I honestly do not know how many chapters I will write but so far it is flowing almost by itself. The first chapter is an intro scene that while not completely necessary, sets up the rest nicely (IMO). Enjoy and please let me know your thoughts.Series

Summary
After the Second Wizarding War stretches on into ruin, Harry Potter performs a dangerous blood magic ritual with Draco Malfoy’s help to go back in time and change the future. Instead of simply traveling back, the spell reincarnates him as Mizar Black-Shafiq, a child born of Lycoris Black, Lord Arcturus Black’s only sister, and Hamza Shafiq.
In the original timeline, Lycoris miscarried after losing her husband to Wane’s Grasp—but Harry’s presence alters fate: one twin dies… and he, with all his memories intact, becomes the surviving son.
Armed with memories of war, loss, and love, Harry must quietly reshape the past. To save a grieving mother. To stop a family’s rot before it spreads. To ensure a future where war never comes.
And this time, he will not be the boy who survived by accident.
This time, he’s the boy who was reborn with purpose.
