Lux Aeternum Patronum (Sevmione)

In a post-war wizarding world desperate to redefine justice, Hermione finds herself caught in the brutal machinery of a Ministry trying to clean its conscience with "projects" masquerading as reforms. When she's summoned to an unsettling meeting, she's not prepared for what they ask of her - or for who they've chosen to be their scapegoat.
Severus Snape, once hero, then criminal, and now forgotten, has been rotting in isolation under a sentence he never agreed to. With Azkaban dissolved and magical law in murky chaos, he volunteers for a mission no one else dared accept - return to the haunted remnants of the prison island to "fix" what the Ministry won't touch. In exchange? A few years shaved off a sentence built on betrayal and silence.
Snape won't go alone. Hermione must accompany him - to vouch for him, and, unknowingly, to confront every buried truth the war left behind.
What begins as a bureaucratic ploy becomes a descent into moral reckoning, personal grief, and the dark heart of magical society itself. How do you redeem a man the world still wants to forget? And at what cost? What awaits them in the old castle?
Azkaban was supposed to break people. But this time, it might finally set them free.
