Chapter Text
Narcissa Malfoy (#myqueen) lies straight out to the powerful legilimens, and also psychotic leader who has been torturing them for a year+, Lord Voldemort, effectively allying herself with Harry, because she dgaf about anything or anyone other than her child.
Unfortunately, her sister notices, and tells Voldemort because she is his most faithful/delusional follower and also she doesn't ever think things through.
Voldemort Avada Kedavras Narcissa and Harry both right then and there and declares victory.
So now they live in the land of doom and gloom where Voldemort reigns supreme and all the heroes are dead or enslaved.
Hermione is given to Lucius – it's more a punishment than a gift, she's a mudblood so she has no value. Voldemort can't just oust Lucius or Draco, he needs purebloods to make his master race, and they still have some friends, but they are no longer in the inner circle. Draco is married off to Ginny Weasley and forced to live in the burrow and Lucius is "awarded" Hermione.
For the first 3-6 months, other than making certain she can't escape, he ignores her. Treats her as a house elf. She fights as hard as she can, refusing to work, refusing to eat, pushing all the wards to their limits, but he doesn't care and it gets her nowhere.
Hermione decides it's time for new tactics. She starts exploring the manor and not just looking for exits. She finds all manner of dark arts devices and a library full of restricted spells and stories. She starts to plot her revenge.
And slowly Lucius starts to notice her. Talk to her. He realizes she's quite intelligent and at this point he's desperate for human interaction.
They start to find common ground. She's going dark and he's ready to retreat to the light. The more they share, the closer they become. He admires her unbroken spirit despite everything, she's touched by the depth of his feelings for his late wife and son. Eventually they realize they care about each other.
But Hermione is still set on overthrowing Voldemort and Lucius has always fought to survive and advance, not to win, and not for any higher ideal.
She wants his help, wants him to join her, to make Voldemort pay for what he did to Narcissa, to Draco, to Lucius himself.
"What do you have left to lose?" she demands.
"You!" he shouts.
Hermione is shocked into silence. Lucius retreats.
In the evening she approaches him. Says "I'm going to move forward with my plan with or without you. You'll have to turn me in, or kill me, to stop me. You might lose me in the fight, but if you don't join me, you've already lost me."
He agrees and they share a passionate embrace.
Using the Malfoy network of shady underground people (which in the Voldemort Wins Verse are the good guys), they amass a mini army. Since Voldemort is Actually Terrible to Actually Everyone, it gains support even within his ranks.
The third Wizarding War takes place, Voldemort is defeated, and, because Lucius is cockroach levels of good at surviving, he and Hermione live through it. Also Draco and Ginny, because their subsequent holidays would be hilariously awkward.
