two nights ago I woke up with the idea that once in a while The Magic calls a very powerful muggleborn to become a pureblood, a sort of first of their name situation; after the call this requires a ritual that requires also a pureblood and results in the two being married.

After the war the Magic calls Hermione, Lucius Malfoy finds out about it, kidnaps Hermione, brings her to the Malfoy sacred grove or something. Draco has been summoned there, arrives, realizes what's happening, tries to run away, gets full-body-bound too, and the ritual is performed.

They find themselves warded in a very newlywed themed wing of Malfoy Manor, with the ability to have visitors, and to receive most of what they want through the house elf (including books from the Malfoy library), but unable to leave, they start cooperating to find a way to undo the ritual.

Narcissa didn't know anything, and allies with them.

For some reason, both Draco and Narcissa's first though is that Hermione should have had the chance to marry Neville, since he's suitably pureblood and a friend. Nobody considers Ron worthy of Hermione :D

Have I been reading too many dramione fics?
