— A/N: Following A Different Kind of Key, I got a prompt for breeding kink with Ominis. I decided to combine this with a fic idea I had included in a poll a few months ago, which was that Ominis kills his parents in revenge, and begins to appreciate the dark arts. I don't know yet how many chapters this will have, but get ready for a dark and manipulative Ominis, and smut 💕 Enjoy, my dears!
It wasn’t like Ominis to say Sebastian inspired him. But that was, in a strange twist of events, what ended up happening.
The day Solomon died changed everything between the four friends involved with it. Sebastian and Anne’s uncle was gone, Sebastian was the one who killed him and Anne was left distraught, their fifth-year-friend was there when it all happened, and Ominis was left feeling like the earth was pulled from underneath him, not knowing where he’ll land. During the following days, Anne buried Solomon and ran. He knew where she was, but was sworn to secrecy never to reveal it to anyone, particularly not to Sebastian. It was a difficult request, but Ominis expected it to be made easier by Sebastian’s inevitable indictment for murder, which was bound to come any day now — right?
Their friend, who even witnessed the murder, refused to turn him in. That left the weight of the choice to Ominis, but he was easily swayed. Why lose two friends when he’s already lost one? So he said nothing…
During the months that followed, the weight of all that happened hung over them like a sword, like a noose ready to drop, like a tipping avalanche. Yet nothing happened. They entered the sixth year, and then the seventh. Anne healed from the curse’s influence — it turned out that Rookwood was the real culprit — and Sebastian graduated from Hogwarts — with the commendations of all their professors — and it had almost escaped Ominis how surreal the whole thing was, but sometimes he reminded himself that Sebastian had gotten away with murder.
It was a struggle to push down just how impressed he was. Sebastian had gotten practically everything he wanted: Anne was cured, Solomon was out of the way in a permanent fashion, and their mutual friend, well, she was under Sebastian’s sway now as much as he was under hers. Complicity did that…
It wasn’t fair. His best friend had a brilliant career ahead of him in whatever field he chose, he had every opportunity now to look for his sister again, and his perfidious little friendship was blooming into a romance day by day — meanwhile, what did Ominis have to look forward to? A return to his parents’ clutches and some arranged incestuous marriage, no doubt.
It wasn’t fair. All his other classmates were cheerful to be done with school, optimistic, hopeful, happy. They had jobs and girlfriends and some were even due to marry. And Sebastian, disgustingly, behaved as if nothing had happened in fifth year, as if he wasn’t a murderer.
It wasn’t fair.
Ominis rode in the cabin with his two friends on the train back to London, where Sebastian was excited to go and apply for a position with Borgin and Burkes.
“You know you’d do better in the ministry…” their friend told him, the smile in her voice teasing but sweet.
“Funny,” chuckled Sebastian.
“You’re still afraid of them?” she goaded.
“I think they should be afraid of me,” said Sebastian quietly, leaning toward her over Ominis. “The score is still one-nill last I checked.”
“Yes, but they don’t know that,” she said, leaning toward him too so that they now hovered somewhere around Ominis’ chest.
“And I plan to keep it that way,” said Sebastian.
“Excuse me,” said Ominis, pretending not to know they were there and getting up briskly enough to knock them back.
“Omi—!”
“Hey, watch it!”
He grabbed his wand and went out of cabin, shutting the door behind him. He pretended to go to the restroom, and pretended to use it for the next 15 minutes, and pretended not to hold back tears of jealousy.
Things only got worse once he arrived home. His parents did not exactly welcome him with open arms, although he had excelled in his NEWTs and was among the best students of his year. No, they behaved as if he’d just been done with a silly distraction, that filthy school that took in mudbloods, and his filthy friends from lowborn families, and now his real life started, said his father, and the fun was over.
He lasted two weeks until he murdered them.
He considered doing it in their sleep, but he wanted them awake. It was the evening of the 17th of July, and it rained and hailed all throughout supper. Ominis pretended to retreat early for the night, leaving them all together in the dining room, tired and mellow with firewhisky.
The doors shut on their own as if by a gust of wind. The chandeliers and fireplace were frozen with a spell. And the dining room was plunged into utter darkness.
A decanter was knocked to the floor and his father was cursing, and his mother called out from the top of her lungs for the elves, but Ominis had sent them away. His sister was rambling something about the house being haunted. They were learning now what it was like for him, what it had always been like for him, although he didn’t imagine they could appreciate it. He cast off the disillusionment spell, he didn’t need it anymore, and summoned all their wands to him wordlessly. Disarmed and scared and in the dark, he picked them off one by one.
First, his sister. He surprised himself by not shaking at all as he did it. In fact, he had never been more calm — was this how Sebastian had felt?
Their mother became noticeably quiet when she saw the brief green light and heard a body fall, but it took a while until she found her, feeling around on the floor. She barely said her daughter’s name in anguish before Ominis killed her too.
His father was left, and by then he’d begun to suspect, calling his name and prowling through the pitch black in that lumbering way he did. Ominis allowed him to hear his footsteps coming closer.
“I know it’s you, you little rat,” spat Gaunt Senior, facing him but standing still. “I heard you say it.”
“And you’ll hear it again,” said Ominis coolly, “right before you drop dead.”
“If only your brother were h—”
“Avada kedavra.”
The flash of green enveloped his body as it collapsed to the floor, and then it was gone, and it was dark again.
Not that Ominis noticed a difference. All he knew now was quiet, and peace, and loneliness. He finally had a life work looking forward to.
The first order of business was to get rid of the bodies, which he accomplished by turning them into teacups and finding a place for them in the glass cabinet in the living room. Brushing his finger across one, he thought it felt different from normal porcelain — a bit more rough, less cold, like bone — but their shape and weight were otherwise quite perfect. He smiled as he put them away.
The next issue was what to do with his brother… Marvolo lived somewhere in London, and he had enough friends there already that his absence would be noted. And he would not come back to the Gaunt manor just because Ominis called. Even if he did, he’d inquire as to what happened to their parents.
Which brought him to the last and final point: how to explain their absence.
He spent the next hour packing their wands, their cloaks, a cauldron, a few ingredients, and a sacrificial dagger, and then he went off into the nearby woods. They sometimes went there to perform spells that called for incantations and ritual sacrifice of the local fauna, often not returning until morning, stinking of wet dirt and blood. He could say a spell went wrong, an animal attacked, and there was no trace left of them but a few less-than-savoury items.
It was quite a trek to make all on his own, even levitating the items behind him, which often snagged in the low branches and the weeds. When he thought he was far enough, he planted the cauldron in the middle of a clearing and stuck the dagger in the earth, scattering the other items all around in what might be a convincing pattern should anyone come look.
Morning found him in his bed, alone and dirty, but content.
Ominis smiled and turned on his back, and listened: quiet. No screaming, no fights, no one ordering him around, no threats of violence, no curses, nothing.
It took about twenty minutes for that to start to bother him.
His fingers toyed with the wand which rested on his stomach, and he thought about all the times he’d judged Sebastian for using the Unforgivables. A part of him still found it abhorrent, because Sebastian was never in such a situation as he had been with his family. However bad Solomon was, he wasn’t like the Gaunts. Meanwhile, another part whispered that he should feel ashamed.
“But I don’t,” he said to himself, speaking with nobody else to hear. “I’m not. I’m not sorry.”
And he wasn’t, for many days to come. When the house elves returned from the prolonged shopping trip Ominis had sent them on, he told him the same lie he had prepared — Mister Gaunt had gone with his family in the woods to perform a ritual but hadn’t yet returned, and Ominis was worried, oh but no need for the elves to go, they needed to tend to the house — and went through the coming days just as he normally would, and soon forgot he’d ever had a family at all. And yet the house seemed larger than before, and behind each corner he still suspected some malevolent force, within each sound a muttered curse or insult, and although he knew them to be safely dead, transfigured in the cabinet, he had moments in the night when he thought they had returned to take revenge.
It wore away at him, and he knew he had to resolve it with a change in circumstance: either he moved away, or he made the house livable again. He didn’t consider even for a second to write to his brother Marvolo, but he considered asking for Sebastian to visit together with their friend — until his thoughts settled strictly on her.
On a whim, he wrote to her, and her alone. The owl took a few days to return, and it brought to him a strangely mournful and yet exciting message.
Ominis had inquired about her health — she was well — and her search for work — not so well — and Sebastian.
“It pains me to say this,” she wrote, “but I do not know. Sebastian has been sent to recover something (I know not what) for Mr Burke. Part of his training, he said. As if he weren’t experienced enough in these sorts of things. I told him, as I’m sure you would have as well, that Mr Burke was only going to take advantage of him and gain a dangerous item at no personal cost, and is only using Sebastian’s goodwill and enthusiasm. He did not take it well and has yet to speak to me since. He said I called him ‘naive’, but I did nothing of the sort.”
Ominis chuckled as his wand vocalised the letter. It was blatant she did think Sebastian naive, just as it was blatantly true that he was.
“To be perfectly honest, I haven’t had a good night’s sleep since, for various reasons,” she continued, “but I find my worries and upsets dwindle into something perhaps similar to what you felt at Hogwarts when Sebastian would get involved in these sort of reckless things — frustration.”
Ominis’ smile broadened. Her clear longing for Sebastian, her worry for his safety, her shameless affection, did not serve him — but frustration, he could work with. He picked up his dictation quill and a piece of parchment and sat down at his desk to write.
“My dear,” he started, “I am first of all happy to hear you are well and healthy, in spite of everything else seemingly falling apart around you. I am sorry, although not surprised, to hear about the novel way Sebastian has found to make a nuisance of himself. You have my full sympathies.
You have also, if you will not find it too forward, my invitation to join me at my parents’ mansion. I think it would be good for you. It is in a quiet and undisturbed area, close to London but surrounded by ancient woods. Without my family present, as they currently are — and we can discuss this too once you arrive — it is a most calming and comforting place, which sounds like just the sort of thing you need at present. You are welcome to stay for the remainder of the summer. It might help you find some balance in your life, perhaps even give you new energies to pursue employment — or other means of occupying yourself.
Please find the address enclosed.
Yours devotedly,
Ominis
P.S.: If indeed he does return in the interim, make no mention of this to Sebastian.”
