Summary
The Marauders used to dominate the high school ecosystem — adored, feared, envied, and absolutely convinced that the central hallway belonged to them.
Easy smiles. Natural charisma. Delusional levels of confidence.
But that’s ancient history now.
Right next to their dignity, may it rest in peace.
After one catastrophic, reputation-destroying incident, they fell off their pedestal faster than a Disney Channel cast entering adulthood.
Now, they’ve been replaced by newer, shinier models.
The Juniors.
Perfect skin. Zero (visible) trauma. Untouched by consequences.And among them, the new king of Hogwarts High School:
Regulus Black.

Summary
In a small town in Maine, Remus Lupin has his routine down. He grabs coffee with his best friend Lily every morning at nine, and then works at a diner in the afternoons until closing, though his boss has now informed him that she has hired someone new, James Potter, who will have the same shifts. One morning, Remus finds himself driving his little sister to soccer camp very late and in a very questionable outfit. When he gets there, the camp counsellor and soccer coach, Sirius Black, stands at the door with a clipboard, crossing off the names of the kids as they arrive.
Sirius, notoriously known for his magnetic personality and the dangerous glint in his eye, goes after what he wants, and when they start "something" -- whatever it is -- with Remus, they both find themselves unable to get enough, even if it was supposed to be casual. Is anything really ever casual, though?
Lots of yapping, lots of joking, lots of nights at the diner eating ice cream and singing, and lots and lots of love.

Summary
The Marauders from their first day of school to their last days on Earth. How they met, how they lived, how they loved, how they died. Their school days, the First Wizarding War, the interwar years, all the way to the Battle of Hogwarts in 1998. Occasional flashbacks and one-shot chapters that do fit into the timeline.
Largely canon-compliant, includes the original HP books/ films with some re-writes for continuity and many original characters.
This does not have a happy ending. I'm sorry :)

Summary
“You used to be fun,” Sirius teased as James reopened his textbook.
“I am loads of fun,” James said, rolling his eyes. “Sorry for wanting to pass my courses.”
“You’re like three assignments behind in one of your classes,” Remus reminded him gently. “You should be opening a textbook too.”
“McGonagall isn't here to save our asses,” Peter laughed, sinking back into the armchair.
“Such a shame,” Sirius said, shaking his head before reluctantly grabbing his own study supplies. “You guys still coming tomorrow? To Reggie's dance thing?”
“Of course,” Remus replied, smiling softly. “We wouldn't miss it for the world.”
Or
James Potter is 99.99% sure he is going to regret everything that's ever led up to this. But what kind of friend would he be if he didn't support everyone else's delusions?

Summary
What if Regulus Black had survived? What if he had been the one to raise the Potter twins?
After betraying Voldemort and escaping the Inferi, Regulus Black vowed to never let darkness take another innocent soul. When fate led him to the orphaned Potter twins—Harry and Ryan—he claimed them as his own, raising them in the safety of 12 Grimmauld Place, far from the watchful eyes of Dumbledore and the dangers of the wizarding world. Under his care, they grew up surrounded by love, protected by ancient magic, and trained in the noble traditions of the House of Black.
But childhood cannot last forever.
As Harry and Ryan enter Hogwarts, their peaceful world is shattered. Whispers of their true heritage swirl through the castle halls, dark secrets of the past begin to unravel, and Regulus' carefully guarded truths threaten to surface. Old enemies lurk in the shadows, and not everyone is pleased that the Black heir is raising the Boy Who Lived.
With the rise of new challenges and long-forgotten prophecies, the Potter twins must navigate their own destinies. Will they uncover the truth behind their past before it’s too late? And when the darkness returns, will they stand together—or be torn apart?

Summary
“My dear child, I cannot control another’s decisions.”
“No? But you can have blatant house prejudices, you can ignore and support house rivalries? You can withdraw help from students of certain families? You sort 11 year old children, and then raise them in a house indicating they have to be a certain way, and never once offer them another option." Pandora argues quickly.
“I think, headmaster,” James cuts in, his voice cold, “that I was wrong to follow you as long as I did, I would rather follow some honest in their opinions.”
“You don’t mean-”
“I’m sure there is a seat at Voldemort’s side for two loyal purebloods.” He states moving closer to Sirius.
It is at this point that chaos breaks out, Barty joining in, “Yeah, fuck you!”

Summary
“Very particular, but loyal. Suited for illusionary magic and games of deception.” Regulus’s wand foretells his future in a single breath when he is just eleven years old.
Year One: Codependence
Coming from a family like theirs, maybe it wasn’t such a surprise that Regulus and Sirius were a little bit codependent. But entering Hogwarts will push Regulus to navigate for himself a world of new friends, a society beyond that of his parents’, and dreams of a strange lake with a glowing green light that calls to him.
Year Two: Mind Games
Walburga Black pushes and pushes and pushes until Regulus’s mind shields can’t take it anymore. They crack—and from this, a terrible, powerful gift is born.

Summary
His eyes scan over the contents until he notices something red with golden stripes peeking out underneath one of Regulus’ shirts.
“Is that my house jumper?” he blurts out.
Regulus stops listing. “No?”
“Yes, it is,” James counters, reaching out for it, ignoring Regulus’ half-hearted protest that he’s mucking up his organising. The jumper unfolds as he holds it up against his chest. “I’d wondered where that had gone. Didn’t know you’d switched houses, Reg.”
OR: Regulus is leaving for his final year at Hogwarts, and James is staying behind.
