Fabian was a nobody once, a squib hidden within Muggles – obliviated by his magical parents and with no knowledge of the magical world. That is until he met a man, a man who is now like a father-figure to him. A man who called himself "master"

Master has taught him magic all those years and Fabian learned. Fabian was a good student and very good learner. They both had a unique relationship of mentor and protégé – it was good enough for Fabian. Fabian didn't want anything but to help and serve his mentor, his master. The Master was a warrior of the light once, until everything he fought for was gone. He didn't say what had happened exactly , just that it was his fault and he came back to fix everything – that's when he told Fabian that he's from the future – Fabian just 15 years old was the weapon a man from the future was planning to use. As 17 years old , he already knew how he's going to die – by finishing something his master couldn't do. Now – 10 years have passed since Fabian found out his mission, they're together in the same room. A cell with no lightness – saying their last goodbyes.

It's dark, the only thing Fabian could see in the darkness was eyes. Green eye , his master's eyes that once were glowing bright – now are just the shadow of his past himself – a great man once he was – a hope of the light side and now he's just remains of that warrior, he once was, a broken man – Fabian now an adult saw glimpses of memories from his master , about the war and the casualties of it and he knew at that moment – another war can't happen and he will stop Voldemort whatever the cost of his life will be. Fabian bows before his master, and listens for the last time what he has to say - just like he always did. Mentor and protégé.

POV OF „Master"

„What...Is...Your" his voice cracks, a long dry cough after that before he can finish the question... „Name? "

Even after all the healing magic, his Fabian did – he still has trouble speaking. His body became weak, just like his mind after he met Fabian and made him his weapon. A ritual to transfer his magic worked, but with great cost to his body – now he only hopes that it was worth it – that after his death tonight, he will meet his parents and they will see together how Voldemort dies once and for all. 'Pathetic, he himself have failed and just can only hope someone will do his job for him'

„My name is Fabian" a young voice answer him dutifully, Fabian was always loyal to him – a curious child once he was, who wanted to learn everything about magic the moment he found out he's a wizard. He still can't forget Fabian's surprised look on his eyes, and how hard was he trying – Harry can only wish he was as hard working as Fabian when he was a child. But now he's not a child anymore – a fully adult by Muggle and wizard standards and he looks like one, he even feels like one. He looks at him and sees Fabian as young himself. There's no scar on Fabian's face, there's no Horcrux inside him – and no reason to sacrifice him – no reason to fail in that. Why then does it feel like training him to kill someone is worse than what Dumbledore did to him all my childhood? 'No, it's not worse. At least he will know what's expected him way before it's time to act. He won't have to choose as the moment's what to do. He will not be cowed like me and will finish his mission.' Harry feels Fabian's presence in the room, Fabian is a very strong wizard now and you can feel his power like you could with Albus Dumbledore and Tom Riddle felt.

"Who... Are…?" He coughs again, harder this time. Fabian pats him; a shiver in his body – He forgot what it feels like, being touched by another human being. He missed the feeling of it, but what he did miss most was the feeling of her hands on him, he still remembers the moment of happiness he felt when she said those two words. "I love you, Harry" She looked at his eyes; he looked at her beautiful brown ones. He kissed her and wanted to answer her same when the Death Eaters came.

"I'm the legacy of Harry Potter, you - my master. My sole task is to stop Voldemort at any cost." He nods to Fabian.

"And… What… Is… Yours… Mission… My… Dear… Fabian?" He stops breathing for a second, waiting for the moment of those words – a climax and the reason he trained young child all those years. His protégé will finish the war against Voldemort once and for all.

"To destroy the last Horcrux, to kill The Chosen One" Harry smiles; he hears the confidence in Fabian's voice and relaxes – another thing he hasn't been able to do those past years. Fabian is ready, Potter line will go extinct soon, but that it is the cost of defeating Voldemort.

*POV OF FABIAN*

In a silence Fabian can hear his master breathing, he finally seems relaxed after all those years and Fabian can't do anything other than smile. Master trusts him, he will finish it. A hero he will be!

"Go now, don't make me force you to keep me company" After many years, this was the closest thing to laugh by his master. Fabian knew one thing – this was the last time he will hear or see his master, a man who saved him from Muggles, who have taught him everything he knew. Harry Potter trusted him with the most important mission in the war and he won't fail him.

"See you soon, Harry Potter" He smiles for the last time at his master, and feels how wind moves him. He's in London now

Destination, determination and deliberation. Fabian now stands in King's Cross station and mentally prepares himself for what's to come.

*POV OF HARRY POTTER/MASTER*

He inhales deeply and looks at the spot where Fabian just was, and exhales. Fabian is not in this timeline anymore and Harry Potter has nothing to do here in the living world anymore.

"I love you too, Hermione" were his last words in this world and he happily embraced Death knowing Fabian will succeed

*POV OF GOLDEN TRIO*

So called by everyone Golden trio have found what the empty compartment seemed after a long walk, and were surprised when there was a man sleeping in the corner.

"Who is he? "Confused boy asked, and neither of other two had answered until Hermione pointed a sign on his luggage.

"Well, looks like our new defense against dark arts teacher this year is Fabian… Potter?" Hermione intently began to stare at the nametag, even more confused than Ron before.

"Harry, you didn't tell me you've had any family left!" Ron said and Harry just shook his head

"I didn't know…" Harry was just as confused as angry by the new teacher.

"Who is he? I can feel his magic all around the compartment" That's all Hermione could say.

Meanwhile Fabian couldn't help, but smile. 'It's going to be interesting year'
