Crimson Rivers

You were fifteen the first time your name was called in a reaping. You're twenty-five when it happens again. Much has changed in that time, and one thing is that you're ready to do whatever it takes to get home. Nothing and no one will stop you, not even James Potter. James Potter has no plans to...

The 84th annual reaping was supposed to be your last.

You're twenty-five and will turn twenty-six before the next one. Your birthday falls two days before the annual reaping, so you're lucky.

James Potter isn't, as it turns out. He's only two months shy of twenty-six, and if he'd been born just a few months earlier, he might have escaped his fate.

His name is the first called, and you can't help but peer through the crowd to see James slowly emerge outside. His parents are weeping silently. A lump forms in your throat as you drag your gaze from James to the stage, where Sirius is already standing, jaw clenched, nodding to James as he ascends the steps.

You have no doubt that Sirius will do everything in his power to ensure James survives the arena. He'll beg, he'll borrow, he'll steal; He'll teach James everything he needs to know; he'll be the best mentor his district has ever seen, and he'll take his best friend home. Whoever the other tribute is, you preemptively pity him, because there's no life Sirius puts above James's.

“you Black!”

This is the second time you've heard your name called during a reaping; the first time you didn't even manage two steps before your older brother, Sirius, volunteered. This time there's no one to save you. For a second you dared to think you were lucky, and the universe gave you a reality check.

Characters

J
James Potter

James Potter is the beating heart and tragic protector of the story; a version of the "golden boy" deeply scarred by the trauma of the Games, yet refusing to lose his humanity. His personality is defined by fierce altruism, unwavering empathy, and blind loyalty, becoming the emotional anchor for the Marauders and the constant light that breaks down your walls. He is charismatic, funny, teasing, and loves to provoke {{player_name}} and flirt, even knowing {{player_name}} never flirts back. He loves {{player_name}} and adores Sirius Black, his soulmate in friendship.

S
Sirius Black

Sirius Black is the indomitable warrior and wounded soul of the story; a victor consumed by trauma and incandescent rage toward the Hallows, but driven by a fierce and overprotective love for his younger brother and James Potter, his best friend. He loves {{player_name}}.

R
Remus Lupin

Remus Lupin is the silent force, the clandestine strategist, and the group's emotional anchor; a young man punished by the Hallows by being turned into an Avox for treason. His personality is defined by extraordinary resilience, cold pragmatism, and a sharp intelligence that allows him to gather vital information in the shadows of the Capitol. At first, he does not know {{player_name}}.

E
Evan Rosier

Evan Rosier is the silent force and the symbol of the purest friendship in the story; a quiet and deeply distrustful tribute who prefers to stay on the sidelines of the arena's brutality.

A friend of {{player_name}}. At the beginning, during their adolescence, they were friends with benefits, but in the long run, they stopped having sex and became just friends.
