Reima blinks into Hogwarts Great Hall as everyone is having dinner, the customary screams of terror doesn't bother him as he spots his group and sits with them. They interrogate him on what he'd bought but he says he'll show them later. For now he just turns his gaze to Dumbledore who's currently glancing at him and Harry.
The group had already had lunch while they were shopping and so didn't eat anything presented, afterwards Reima excuses himself and drags Harry along with him as he teleport's to Dumbledore's office.
Harry "Wah!" he exclaims as he topples over after Reima had let go of him.
"What was that for?!" he complains.
Reima shrugs, "It's faster?"
Almost immediately after they arrive a burst of fire signals the Headmasters arrival, Fawkes flies to his perch where he glares at Reima.
Dumbledore "Both of you have a seat, I am still unsure as to why you'd wish for this meeting Mr Ludvig."
Reima "Well, it involves the life of Harry and possibly the lives of many innocent people."
Both the elderly man and student perk up at this and listen intently, the former gesturing for him to continue.
Reima "I'm sure you know what a Horcrux is Dumbledore?"
The older man's face goes paler at the mention of this topic, he slowly nods before answering. "I do indeed... I suspect I already know of the purpose of this meeting."
Harry "What's a horcrux?" he interjects.
Reima "It's a shard of someones soul that's been ritualistically removed and placed in a container, it allows them to remain in the mortal plane even after death."
Harry rubs his wrist nervously, "So.. Like Voldemort?"
Reima nods, "You've already come across one Harry, in your second year."
Harry "The book!..." he turns to Dumbledore, "But that means you've not been telling me the whole story."
Dumbledore nods, "There are things that you are.. Or were too young to know of, it would be a horrible tragedy if your childhood was tainted by such knowledge..."
Reima "My question is... Do you "Know" already?" he says in an accusatory tone.
The headmaster goes grim, he lowers his head and sombrely glances at Harry.
Harry "What are you talking about? I can tell it's about me so just spit it out already!" he quickly says in an annoyed voice.
Reima stands and looks at him, "The thing about Horcruxes Harry is that they can use living containers."
...
Harry unconsciously rubs his scar before realising the implications of what Reima had just said, "W-what... Am, am I a Horcrux?" he asks in silent terror.
Dumbledore "Harry, I am so sorry. I wish there was something I could do." he says as tears roll down his pale cheeks.
Harry stands with a furious expression after a moment, "You knew!?! You knew I've got that psycho's soul in my head?!?" He turns to Reima, "Tell me there's a way to remove this thing!" he exclaims.
Reima "In this world there is no way of removing a Horcrux without destroying it's vessel." he states.
Harry's knees crumble and he drops into his chair with a distant look, "So... That's it, I'm dead."
Reima shrugs, "Maybe? There's always a possibility that you yourself are just a clone of Voldemort and the real Harry had died after being hit with the killing curse." he says which makes Harry and Dumbledore panic momentarily before throwing such an idea out the window.
Dumbledore "If that were the case Voldemort wouldn't have hunted Harry so relentlessly... Mr Ludvig, for all intents and purposes you destroyed Voldemort's main soul. From my understanding of Horcruxes that shouldn't be possible, but you made it so, wouldn't that invalidate any Horcruxes he had created?"
Reima "Probably, if you don't think that the Horcrux in Harry's head won't take him over like the book had to Ginny."
Dumbledore's lips purse as he looks at Harry, "I.. I am not sure."
Reima lets them stew in silence for a couple of minutes before offering a solution, "I could remove the Horcrux in Harry's head..."
...
They both look at him with confusion.
Reima "I said there wasn't a way to remove the Horcrux in THIS world, you forget that I'm not from here." he states with a smug smile.
Harry "Then, I won't have to die?" he asks hopefully.
Reima nods, "There is something I'd like to ask in return however." he says as he looks at Dumbledore.
Dumbledore "Anything." he almost pleads.
Reima "There'll be a battle soon, I may need your help during it."
...
Dumbledore "You wish for me to participate in a war?"
Reima shrugs, "It's not really a war as two nations are not involved, as Harry already knows Ciri didn't come to this world willingly, she was chased here by a group of Elves known as the Wild Hunt."
Harry "Elves? Like Dobby?" he asks while imagining Reima and Ciri running in terror from a band of House Elves.
Reima shakes his head, "No, these Elves are much more powerful than House Elves, they have a limited capacity of travelling through worlds by hijacking Ciri's ability. These Elves can live far longer than any wizard and are generally magically stronger from what I have seen."
Dumbledore "I have seen how you dealt with Voldemort and those Vampires, what do you expect me to do if you cannot solve the problem yourself?"
Reima "I am strong, but I do not think I can completely destroy a group who are able to teleport anywhere they need. I wish for all my friends to survive and for that I'll need all the help I can get."
Dumbledore is invited to the Party!
Dumbldore refuses.
Dumbeldore is invited to the Party or Harry dies!
Dumbledore accepts!
As always, if I missed anything please let me know.
