It starts the same as above, with Fleur and Harry as cursebreakers and Harry dying to a particularly nasty dying curse of a defeated necromancer. Fleur panics, the bond between them shatters, her mind… cracks. She performs a necromantic ritual, bringing Harry’s soul to his body. It seems everything went fine and nobody notices. They go on with their lives, yet some vital part of their relationship is lacking. On the next expedition, Harry dies again due to a freak accident and is brought back by Fleur. This occurs a few times.
After some time, Harry starts noticing something is amiss, his memories, his personality, every time he comes back, he comes diminished. Fleur refuses to see. Eventually Harry tries to convince Fleur to let him rest, but Fleur is adamant. Harry keeps dying and being brought back, existence with Fleur becomes a torment. They are pursued be strange beings, agents of Death, meaning to restore the natural order of things. Eventually, Harry cannot bear to see Fleur inflict this torment on herself and seeks to end his unlife. After succeeding he begs the agents of Death to bring him to Death itself. Harry strikes a deal, entering into service in exchange for protection from being raised again. He accepts the mission to hunt down Fleur. Fleur meanwhile was growing increasingly desperate as her ritual stopped working. Upon hearing the beloved voice whispering her name, she looked up and beheld her Harry returned to the world. She jumped into his arms, forcing him into a kiss. Next thing she felt the cold bite of steel, as a razor sharp edge entered her heart. In Death’s court, shattered by this final betrayal, Fleur’s soul is a pathetic wretch, about to be sentenced to an eternity of suffering. Yet Harry intercedes, begging Death to give Fleur another chance. A bargain is made. For every instance of Fleur violating the laws of existence, a century of faithful service or one sinner in the same vein brought to justice.
