Summary
Regulus was not doing okay. In fact, he's having the worst time of his life actually. He is intelligent, cunning, the epitome of the Slytherin he knew he was, he was the heir of the Ancient and Noble house of Black. This reality shatters when he awakes to a different world - a life without magic. He's the only one who knows of magic and holds it like a weapon. With 'his' family's attention on him, he finds an unlikely ally in James Potter who is now a muggle. Of course he did, just his luck.
James Potter dreamed of the stars and the unknown and an unhealthy fixation on all things magical. He never indulged his interest in the fantastical to his friends, so imagine his surprise when his best friend's younger brother done real, actual magic in front of him. He takes it upon himself to help Regulus come back to his own realm while trying to do magic himself, but what happens when he realises he doesn't want Regulus to go back at all?

Summary
Normal People AU. They want each other. That’s never been the problem.
James turned, slowly, as if dragged by something heavier than guilt — something ancestral. His hands remained in the pockets of his borrowed jacket, a gesture both casual and cowardly. The streetlight above them flickered, catching the edge of his profile like a sketch someone had given up on finishing.
“That’s not what happened.”
Regulus laughed. It came out dry and scalpel-thin, a single breath honed into dismissal.
“No?” he said. “Because it felt a lot like you were pretending I didn’t exist.”
James looked at him then — really looked. Not the kind of glance you throw over your shoulder to see if the past is still chasing you, but the kind you give a painting you’ve stared at a hundred times and only just realized was about you.
“We were with my friends,” he said, as if that was a reason and not an excuse.
“And I’m not allowed to know you when they’re around? Do you have any idea what it’s like? Standing in a room and having you look through me?”
There it was — not a plea, not a break, but something far more dangerous: a mirror.

Summary
When the Black family leaves France for a quiet lake town in Vermont, young Regulus learns early that silence is safer than softness. His world becomes the walls of his home, his lacrosse stick, and the distant laughter of his brother Sirius with the boy next door—James Potter. Years later, at an elite boarding school, Regulus’s resentment festers as James and Sirius’s bond deepens, leaving him on the outside looking in. But as time, trauma, and growing up reshape them, the walls between Regulus and James begin to crack.
Through starlit practices, unspoken apologies, and a single offered hand, Regulus grows from a boy haunted by his parents’ shadows to a young man learning that love—real love—is not control or perfection, but a quiet choice to stay.

Summary
Raima Patil is the Head Girl and a master Arithmancer whose world is defined by cold, efficient logic. When a political enemy threatens to ruin her powerful family, Raima is forced to ally herself with the most volatile variable she knows: Sirius Black, the school's rebellious chaos magnet.
Their reluctant collaboration forces Raima to break her own rigid rules, leading them into a high-stakes Ministry heist and an undeniable, consuming tension. Along the way, Raima, recognizing the calculated survival of the marginalized, forms complicated alliances with Severus Snape and Regulus Black, seeing the humanity in their trauma where others see only malice.
This is a story about the complex mathematics of morality, the terrifying nature of vulnerability, and realizing that sometimes, the most logical choice is to embrace the Chaos Variable.
