Summary
For the record (and this has got to be said), Gwaine had a pretty normal childhood. Sure, his family was a Wizarding family, and he remembered bits of a past life, but humans can adapt to a great degree.
Up until the premeditated murder, at least.
Or.

Summary
At five years old, Dahlia knew three things about herself:
• She was a twin
• She was a Dursley
• She was a witch
She was never sure which was the hardest to contend with. If she was truly being honest, though, she might have said that it was this:
Life is sudden and terrifying, and it doesn’t get any easier the second time around.A self-insert dealing with mental illness, social structures, and the implications of dying and becoming a character in a book.

Summary
When he’s ten, Orion recognizes Slytherin’s locket in the drawing room, lost amongst other nicknacks and cursed items, knowing better than to touch it.
He stares for a long while, wondering how he could’ve forgotten, before turning on his heel.
He remembers the story. How can he not? But it’s fragmented and jumbled in his head, blurring with what he knows of this life and the details he does recall don’t concern him.
There’s only so much one can remember about a book read a lifetime ago.
Orion has no interest in getting involved.
He has a life. A name. A duty to his family.

Summary
Ari figures that finding herself in the world of Harry Potter with memories of things that haven't happened yet is a big enough plot deviance that she might as well go ahead and change everything else.
Now she has to plot several rescues, look for at least one competent adult, and find the nearest library. Hopefully before anyone figures out just how much she knows.

Summary
Children’s hair sometimes changes color as you grow. When he’s young enough for it not to be unusual, but old enough to know he’ll get in trouble for doing something ‘freakish’ again, Harry's hair goes from his father's dark locks to his mother's bright, most-likely-magical red hair.
It changes everything about who he identifies with, who he wants to grow up to be, and who he thinks he is. Instead of having James Potter as his idol, Lily turns out to be a much better influence.
So instead of seeing a scruffy, most-likely-muggleborn boy standing beside him in Madam Malkin's before their first year, Draco only has eyes for the scarlet-haired, green-eyed creature who just walked into his life. Not that Harry will ever notice, given he's trying to simply survive Hogwarts.Story Discord: https://discord.gg/8b7zt5PBHp

Summary
“Am I dead?” he asked, because he should be dead. He should be at the bottom of that lake, drowning under the bodies of decomposing inferi, but—
“Calm down, Black, you only fell off your broom."
—instead he was two years in the past. Alive. And with a whole new mess to deal with.
or; it's back to time travel, baby!

Summary
“What I find absolutely fascinating,” Riddle said, stalking closer, “is you.” He marched forward, backing Harry up until he was pinned to the cool wall of the common room. “Do you know why?”
“No. And I’ll be honest here, Riddle, I don’t particularly care.”
The taller boy grinned at him, small yet infinitely pleased. “That. Right there.” One hand rose and brushed some of Harry’s fringe from his face. “Nathan Ciro was a spineless little boy too afraid of his own shadow to dare even glance in my direction. But you…”
He leaned closer, “You look at me like you want to stab me.”
After an accident, Auror Harry Potter wakes up in the body of fourteen year old Nathan Ciro, a tormented Slytherin who recently tried to end his own life. Seeking answers to his strange predicament, Harry returns to Hogwarts, and causes quite the stir through staff and students - especially when they come to realise he is not the same boy as before.
He tries to avoid suspicion, but as his quest for the truth draws more and more attention to him, Harry begins to think that he might not like what he will discover.
