Neymat- Snupin Drabble
Remus looked at the Horcrux in his hand. It was such an insignifigant little thing, just an ordinary diary - something that could be purchased from any stationery shop in the world. But this diary was an important part of Remus' life. Now because it held the soul of his mate and one-time lover, Severus Snape but even before that, this little book had been important.
It had fallen into his possession through Fenrir Greyback. Though Remus hated everything about the side the man was on, he couldn't truly hate Greyback himself. Werewolves were pack creatures like their wolf cousins and in those terms, Greyback was his father for he had sired him by biting him and turning him into the monster that he now was.
Greyback had given him the diary, asked him to keep it as a favor and had promised to stop trying to pull Remus over to the Dark side, to stop trying to build a type of relationship with Remus, to leave Remus alone to live his life and Remus hadn't been able to refuse. He'd taken the diary and locked it away under the strongest locking charms he knew. He'd made sure that only he and Greyback could retrieve it and then he'd gone on to live his life, never thinking about the diary until Greyback asked for it five years ago.
The diary had been used by Lucius Malfoy to try and discredit Arthur Weasley but it had nearly gotten Harry, the only thing left of his best friends, killed. Remus had berated himself for being so stupid as to try and honor a promise to Greyback and vowed that he would never help the alpha again. But when Greyback had come back, he'd given in to keeping it again. It had taken a lot of persuasion, though and had required Greyback to explain to him exactly what was so bad about the diary even now, once the piece of Voldemort's soul had been destroyed.
'A Horcrux container has been inhabited by a magical preson's soul. It has absorbed some magic from that person and therefore this container can be used to contain the soul of a dying person so that it can be put back into a body if the damage to their body can be repaired or if another body can be found. Do you understand what I'm saying? It will allow a dying person to be saved either by letting them be sent into their own body or into another body that has recently lost it's soul. This is dangerous Remus and if it is studied, it can teach any half-decent witch or wizard how to keep themselves alive indefinitely by possessing Dementor victims. I don't want this knowledge to fall into the hands of the wrong people. Please, Remus. Please keep it for me.'
And he'd agreed. Not only because he realized that while those who wanted immortality could achieve it by creating Horcruxes, this method could allow a person unsuitable to perform such magic to become immortal if they got their hands on it but because his wolf side had been urging him to help Greyback and he hadn't had the energy to refuse.
Now, five years later, he was sitting with a diary that had his lover occupying it while he and a St. Mungos team worked frantically to repair his body - they didn't know whether Severus inhabiting a Horcrux would harm his soul but had decided to work as quickly as possible nonetheless - and a pressing need from his wolf to thank his quasi-father for helping him, however unintentionally.
