I finally have Seven mapped out the way I'd like it to go. So I revised the summary for new readers. I was thinking Succession but for a powerful magical family.
**Se7en – A Dark Severus Snape x OC Fanfiction Summary**
In the shadowed corridors of power where ancient blood meets ruthless ambition, the Gaunt family is rebuilding its empire from the ashes of defeat. At the head is the patriarch — a once-fallen tyrant returned sharper, colder, and more calculating than ever — determined to secure his legacy through any means necessary.
His twin heirs embody the family’s fractured soul: Roman, the volatile, magnetic son groomed for violence and command, and Annabelle, the brilliant but fragile daughter whose psychological battles make her both a vulnerability and a weapon. Caught between them is Severus Snape — the brilliant, tormented son-in-law whose loyalty is as strategic as it is obsessive. He navigates the deadly tightrope of serving two masters: the Dark Lord he swore allegiance to, and the wife he would burn the world for.
This is a story of inheritance, control, and the corrosive price of power. Every dinner table is a boardroom. Every conversation is a negotiation. Love is leverage. Betrayal is currency. Blood is the only thing that truly binds them — and the only thing that can destroy them.
In a world where weakness is fatal and loyalty is conditional, the Gaunts don’t just play the game.
They *are* the game.
