This is another idea I don't think I've get around to. Also if any of the story's are adopted will be in the another's notes at the end of each chapter along with the story name that is adopted(this will hold the information about who adopted it and what it is called) this story is a RWBY(minor) and Harry Potter crossover also the events of Harry Potter starting with the first blood war(Voldemort's first raise where pushed back with Harry born in 2006 instead of 1980 )

Ten year old Harry Potter shivered in this cold cupboard the draft pentrating his thin blanket that had been with him for as long as he could remember. Not that it was helping him much here caked in both dry and fresh blood. Rendering what little protection it normally gave moat.

He thought back to the night before the Dursley's had left Harry in the house alone as they hadn't been able to push him on to anyone else with Mrs Figg sick and all the rumors that they had spread about him to the rest of their neighbors. They had also not locked him up in his cupboard having left him to do chores in the house. After he finished he had been bored and having been warned not to watch the TV or else and that he had better be up when they got back in a week or two. So thinking of things to do he remembered Dudley talking about RWBY with his friends at school and how awesome it was and that he loved youtube for showing it.

After a few minute he decide to go watch it His Uncle Vernon and Aunt Petunia had never said anything thing about Dudley's computer. So taking up his rations of bread and a bottle of water he left for Dudley computer. He quick found the series and watch it entrenched and enamored unfortally for Harry the Dursley's had got back early having realized that they had forgotten their reservations. And his Uncle had walked in on him as the fight scene between team's RWBY and the nevermore with team JNPR having just dealt with the death stalker(he had finished the series and was just watching over it for the second time).

His Uncle had when ballistic shouting out about their being not such thing as magic and that obviously he had not been able to beat the freakenshes out of him yet. After that it had just been pain and shouting before the light cut out and the door had slammed shut. He now knew that he had been shut in his cupboard. Not that it mattered

He felt the intense pain in his right arm and left leg and the slow numbing of everything else as his blood leaked out of his noise and from the numerous cuts covering his body. Slowly the world was fading and the pain felt less and less. He didn't know how long it had been but his throat felt parched and their had been a hunger gnawing at his stomach but that like the pain had numbed.

He knew what was happening and that nobody was going to help him. Well at least he'd be with his parents soon... maybe they would love him unlike his 'family'. But that was only looking on the bright side of things Harry didn't want to died for one it would be like the Dursley's won. He thought that maybe if aura had been real he could have used it and for a second he wished it was. And with that last thought Harry James Potter fell unconscious not knowing of the reaction his wish would have upon his currently unknown to him magic.

Harry's magic had been under a lot of pressure with a large block in place. Put their by Dumbledore in an attempted to cut down Harry's accidental magic. However that was not the only pressure the blood wards where draining Harry's magic to sustain itself. This was not mean to be the case love is a powerful magic that can do incredible things but with no love between Harry and the Dursley it had instead of being empowered by their blood relation it had instead weaken it and the ward had sensed the dark presence in Harry's scar and attempted to help but to do so it needed power. Power which it was unable to get from where it was meant to so instead it drain power from the only magical being in the house. Not only was the block preventing access to most of his core but the power drain for the ward's wasn't the only drain the dark and evil presence of Voldemort's horcrux had been draining even more magic to sustain and empower itself so as to possess it's new vessel. But Harry's own magic had recognized the intruder and the harm it meant to it's wielder and began a full out assault with what little it could access in an attempted to kill the intruder. But with Harry so close to death it also tried to heal the broken body it was in. Leaving it unable to keep up it's normal protection.

Of which the Parasite that was the piece of Voldemort's soul stuck in Harry's head took full advantage of in it's attempted to take full control. Initiating a full soul to soul war. A war in which Harry had been slowly losing. Until the full might of the blood wards brought itself to bare as it found it's fuel and lone occupied at the time under attack. Under the full power of even the weaken blood wards the pressure on the block on Harry's magic burst combined with the magic of Harry's core desperation to help protect it's wielder. And with the fresh and massive increase in power the shear amount of power overwhelmed the tiny piece of soul from Lord Voldemort destroying it completely. Next Harry's magic took in the blood wards it then cut the connection it had with number four privet drive. Sensing the hate and dislike of the location and of the three non-magic's it's host had. so why would it protected them for nothing in exchange for it's wielder. It then tied it to itself when it felt the original power behind the wards.

However Harry's magic had a problem even as it heal him both body and soul there was just to much power to be contained in the body of a ten year old. Harry's magic had to over produce for so long to get such a small amount of power available for use that when unleashed the power itself started to burn through the body and soul. As it search for a way out of what happen it caught Harry's last thought from before. And it hit the jackpot linking the soul and body in such a way as to grant what it's host had seen in the show it had watched for the idea would be a extremely costly especially to grant the ability to be able to 'unlock' others and for them in turn to be able to 'unlock' others. It would take a total rewrite of both the body and soul as well as linking itself much more closely than it is currently to do so and to grant a semblance... which even for the ungifted would come about in time after an 'unlocking' as it would develop from the soul or combine with it depending on if the user had been gifted or not to start with. after all that is how magic is made for a magical being anyway. it's made from the soul(apart from with house elf's which where magic as they draw magic in from external sources).

So it does so pushing the soul and body together allowing the soul to empower and shield the body and the body to empower and shield the soul(in doing so rendering the killing curse unable to work on the 'unlocked' as the soul is to closely linked to be able to be force out of the body). As it feels itself starting to combine with it's wielders soul it pushes the glyph semblance along with dust creation/manipulation into it's wielders soul and making the semblance heredity with the dust creation/manipulation being copied to any 'unlocked' by any who have dust creation/manipulation being that the dust created is purified 'aura' which leaks off creating dust by the shear presence of the 'unlocked' along with being able to concisely produce dust for using 'aura' to do so.

This was just my thought of an rwby-Harry Potter crossover that doesn't have Harry just go to the rwby universe and instead it has rwby powers brought into the Harry Potter universe. The bit at the end was the only way I could think of to have dust come to the Harry Potter universe easily the only other way would be to make Harry extremely Rich and experiment with precious stones to turn them into dust.
