Kakashi blinks, not having expected a legitimate response to his half-hearted question, much less two replies. "I don't know what either of those things are."

Voldemort leans back his chair. The silver haired man is a muggle, but the Dark Lord isn't one to restrict himself with laws like the Statute of Secrecy. Plus, he's feeling rather charitable after hours of devouring information.

The Dark Lord falls into lecture mode with ease despite not teaching since Hogwarts when he was playing the good student and helping others. "The Veil is an unidentified magical phenomenon, theoretically able to move past the ley lines that hold physical matter in this universe. If utilised properly it can be a vessel to transport matter to an as of yet unknown location."

The ninja raises an eyebrow. "You could have just said 'mysterious portal'."

Voldemort scowls. "It's much more than a mysterious portal you-"

"Well," Reborn begins in the exact same lecturing tone, loud enough to drown out the older man. "The Sky Mare ring can allow the user to view and -with the proper equipment- step into parallel worlds." The hitman slides a superior glance to Voldemort. "Theoretically and experimentally proven, by the way."

Voldemort narrows his icy blue eyes. "Don't disrespect your betters, little boy. I've crucio'd someone for far less."

Kakashi cuts in quickly, wanting to know a potential way home before the fighting starts. "How does it work? Can you show me the ring?"

Reborn pauses. "I don't exactly know where it is… or how it works."

Voldemort scoffs. "What happened to 'proven'? Don't tell me you're going off rumours."

"Still better than a mysterious portal," Reborn argues.

"It's not a mysterious portal," Voldemort snaps and the wand comes out, a toxic green glow building at the end of the intricately carved wood.

Leon is sliding out of Reborn's sleeve in the next second and transforming into a gun as the hitman lines up the shot with Voldemort's head, not a hint of hesitation as he tightens his hold on the trigger, ready to react as soon as the older man makes a move to use his strange weapon.

Kakashi very calmly flips the table.

Reborn and Voldemort lurch to their feet and move back to avoid getting crushed under the heavy books and solid wood. The hitman quickly grabs his tossed laptop mid-air and catches his hat on the shut lid.

A loud series of 'thud's echoes through the library and Voldemort grimaces at the bent spines and scrunched pages of the books underneath the table. It's like nails scraping down a chalkboard to him.

"Maa, maa," Kakashi drawls, still slumped in his chair. "Let's not get too excited here."

"You're the one who actually moved first," Reborn says, an amused quirk to his lips as Leon retreats up his sleeve and he places the hat on his head.

Voldemort clicks his tongue but reins himself in and flicks his wand a few times, levitating the mess back into place and fixing any damage while ignoring Reborn and Kakashi staring with curiosity.

The Dark Lord then turns to the other two and holds out a hand. Reborn blinks innocently but hands over the notebook that he was hiding. Voldemort snatches it away from the infuriating Italian and turns to Kakashi, who produces a fountain pen. The wizard tags a portkey to them both before dropping the research notes and watching them vanish mid-air.

"What do you call the power you use?" Kakashi wonders.

"The broad term is magic," Voldemort admits, smoothing down his button-up shirt – not that it has wrinkles. "It tends to have a bad effect on technology so you might want to check your device," he adds on with a gesture to Reborn's laptop.

"Don't worry," Reborn says dismissively. "It's unbreakable."

Kakashi is rising out of his chair and wandering over in the next second because as a ninja he has never encountered something that can't be destroyed. In fact, he has the unfortunate tendency to break things he's not supposed to touch (Rin is a good example of this). "What is it made of?"

"That's a secret," Reborn hums teasingly and passes over the technology.

Kakashi takes it and scans the thing before opening it up. He presses down at a corner of the keyboard, where it could still be fixed if Kakashi accidentally goes too far with his strength, but it doesn't dent.

He blinks his one eye in curiosity and applies more force, still rather hesitant at damaging the thing since the black-haired man seems nice (In the loosest sense of the word. Kakashi remembers the sleek weapon and the smooth way the man reacted).

The technology doesn't so much as strain under his chakra reinforced strength and the ninja guesses at something like high-tier fuinjutsu. "Not bad," Kakashi admits and returns it.

"Fiendfyre."

Reborn and Kakashi jerk back while the laptop, right in the middle of exchanging hands, clatters to the ground as a roaring fire shaped like a snake engulfs it. The device disappears under red and orange and heat.

Voldemort smugly snuffs out the flames with a dramatic swish of his wand - and then blinks at the perfectly whole technology sitting innocently on the scorched black carpet of the library, a hole almost burnt straight through the floor under the laptop with dark smoke rising in wisps.

Reborn smirks and picks it up, bracing it on a hip with one arm, his other hand tucked into his pocket. "Neat trick," he says, humouring the man out of pity because Reborn's fire is much hotter than that tiny flicker.

Voldemort doesn't even care that the youngest is looking patronising because Horcruxes can only be destroyed by three things. Repentance, which is a joke in itself. Basilisk venom, which is rarer than a competent Minister of Magic.

And Fiendfyre, which any idiot can cast if they know the wand movement and the words. It's the greatest threat and nothing can survive it - except apparently this man's laptop.

"What material is that?" Voldemort murmurs, eyes alight with a dark shine.

Reborn doesn't answer and instead turns to Kakashi, calmly stating, "I want to see where you came from."

The ninja glances between the two men and his eye crinkles up in amusement as he catches on to the youngest one's mischief. "The portal of yours sounds rather interesting, doesn't it?" he asks Voldemort.

The Dark Lord calmly debates the pros and cons of just killing the silver haired one and ripping apart the black haired one's mind. He does a cursory glance with Legilimency and encounters absolutely nothing. Voldemort could have been trying to use Legilimency on a lamp for all that Reborn gave up.

That's not a good result at all. Imperio won't do anything on someone like that and a person with dealings in mind arts can shut themselves down when forced to drink truth serum. Voldemort could kidnap and torture the man? That's always an option.

Except no, it's really not, because torture is so crude for something this important and Voldemort can't break the Italian before he gets the name of the material.

So the question is; how much is the information needed?

Dumbledore, really the only threat, is slippery enough and has more than enough contacts all over the world to be able to piece together Voldemort's source of immortality. From there it's only a few short steps to find which objects Voldemort used (he wasn't exactly being subtle with his choices).

Perhaps the Dark Lord is paranoid or his view is biased since he already knows where the Horcruxes are, but he's not going to trust his immortality to 'hopefully Dumbledore is too stupid to piece things together'.

Then the next question; what is the price that will be paid?

Clearly Voldemort will get the material last which means showing the silver haired man the Veil. The hard part comes with the Italian's request, 'I want to see' being the words, which refers to actually visiting an entirely different dimension.

Theoretically it can be done since the silver one is here (and maybe isn't just insane) but theoretical doesn't count for anything if Voldemort can't put it into practice. Oh, he has no doubt in his mind that he will be able to if he puts effort into it, but he's kind of in the middle of a war so side projects should wait.

The last question seems to be; is the price worth the information?

"Yes," Voldemort says.

"Wonderful," Kakashi chirps. "So, we should all go see this interesting curtain." His mask moves like he's grinning and the ninja slings a long arm around Reborn's shoulders. "I feel like we'll be great friends - actually, what's that saying again? It means 'three'?"

Reborn raises an eyebrow, not sure what Kakashi is talking about but willing to guess anyway. "Do you mean a Triumvirate?"

"No, no, it's something like…" The ninja snaps his fingers in realisation. "I remember! It's a ménage à trois!"

"No," Voldemort deadpans instantly. "No, I assure you, that is not the phrase."

"I'm pretty sure it is," Kakashi argues, still with that irritating eye curved up in amusement.

"I'm pretty sure you're a piece of-" Voldemort cuts himself off because he needs to learn to control this explosive anger. He takes a deep breath and lets it out but none of the sudden rage leaves him. "You die first," he snaps at Kakashi and then turns to Reborn. "You die second. Slowly."

"What did I do?" the hitman protests half-heartedly because he knows exactly what he did and he does not regret the chaos.

Voldemort hisses wordlessly.

A/N: I'm not continuing since I have no idea where to go with this (sorry if I got your hopes up hahah) I just didn't want to post only a note.

RyuuSiren7 has actually adopted Triumvirate; called Ménage à Trois. Find it in my favourites list.

If anyone else wants a go at this plot then the offer of adoption is still open (I kind of want to see the different routes this will go under different authors).
