Moments later ten year almost eleven year old Harry James Potter shot up on the filthy and thin mattress in the cupboard under the stairs. Hearing soft clattering, his hand sought out in the darkness. Finding the metal wand, plus his old Holly and Phoenix. Which hummed happily in his hand, happy to be back with its true master and not the false one that had claimed his wand in spoils of the war. His grip closed around the six inch obsidian stone wand. That wand he spent nine years crafting in Azkaban. It had only one master and would only react to the one master who made it and wielded it.
Leaning against the wall of the cupboard, he gripped the three wands in his hands tightly, almost fearing if he allowed them out of his grip, he would wake back up in Azkaban.
As he turned the light on, noting on the ceiling of his 'room' had the same pentagram that he had used to send himself backwards in time. The grin that crossed the face of the tiny ten year old was terrifying in it's feral intensity. It worked, he had done the impossible. Sending his adult mind, core and magic back into his younger self. Getting to his feet, he pressed the obsidian wand to the locked door. Before vanishing the offending piece of wood.
He had plans to enact, Horcruxes to hunt and destroy. He would be no puppet on a string, tonight Riddle would die. Apparting noiselessly, he appeared at the shack in which housed the ring. Tearing down the wards with ease, he strode into the shack. Before finding the hole where the ring is at. Tossing a killing curse at the offending object, smirking as the soul screamed as it died.
Tucking the ring into the pocket of his baggy jeans. Apparting to Hogwarts, bypassing the wards and appearing in the room of requirement. Finding the diadem, he threw another killing curse, tucking the diadem into his pocket. He then apparated into the chambers. Releasing the Basilisk from it's binding. Maybe this way it would be gone when he arrived.
Feeling magic, he popped in a room in which held the mirror. Shrinking said object, he tucked it in a pocket. Apparting to Malfoy Manor, bypassing wards, to appear in the room. Finding the journal, he destroyed the horcrux. Appearing in Gringotts, in Bella's vault. The smile on the wizard's face was dangerous. Laying down suppression wards, which would keep Bella and anyone of her line out. He dismantled to Gemino curse on the chalice. Casting the killing curse, apparating out of the vault. Another day he would come back and get his vaults back under his control.
Now onto Nagini. He located her in a forest in Albania. Along with the wraith Riddle and the useless Quirrel. Killing Quirrel before Riddle could take control, then killed Nagini. Smiling fiercely as the shade was dragged screaming into Hell. That took care of that problem.
Apparating back to the Dursley's. Remaking the door before he decided to finish his tasks. Apparating back to Gringotts, getting all his vaults back under his control. The key-chain which held over a dozen or more keys. Which jangled merrily in his pocket. The Black vault in which he stood in, had mountains of books. Finding a library trunk, he began whittling away at the mountain of books, storing them away. In the Emrys' vault he found more books. He grinned, this would be a start of a new start. He knew he had a couple of months before his letter arrived.
Clearing all the vaults of their books, including the founder's vaults. This time around he would be at the top of the classes, not Granger. Shrinking the library trunk, tucking it into a pocket. Before apparating away. Reappearing back at the Dursley's house, he went back into his cupboard
Casting a lumos, he sneered at the state his room is in. Casting an enlarging charm on the cramped quarters. Soon it looked like he is in a master bedroom suited for a King. The bed, a massive thing which would hold ten people comfortably.
The dresser, which now held clothes that he conjured and made permanent. Plus a walk-in closet which held traditional wizarding wear. A trunk, which he would consider his greatest achievement. Right after his stone wand. That was his proudest achievement even in prison. He had spent months chiseling out stone from the wall in a rough shape of a wand. Then spent more months channeling his magic through the stone, focusing on his magic to imbue the stone with magical properties.
As he stood up, moving towards the massive trunk. It stood about four feet high, with the lid closed. Three feet across and four feet deep. It is a masterpiece made of wood, stone and metal. The wood a deep rich reddish tone, the hinges made out of pure gold, the foot-stand out of marble. Emblazoned across the lid in golden overlay is the Potter, Peverell, Black and Gryffindor crests.
Looking like a normal Hogwarts standard issued student trunk. But within the trunk is nine levels. The first is the standard size of a Hogwarts trunk, which would hold his everyday things from parchment and quills.
The second is a walk-in study/library compartment. That would hold all the books he would be buying. Plus any other books he would find in the Normal world. Before his immurement, he had been reading the Lord of the Rings Trilogy and had been getting ready to read the Hobbit series and the Simillarion.
The third is a walk-in changing room/wardrobe. His clothes would go in there, plus all his footwear. He wouldn't even consider using money to buy the clothes when he could use his magic to conjure up clothes that would last him an entire lifetime.
The fourth is a training room. Which would let no one know of his use of magic. He wasn't planning on being the boy he had been in his previous lifetime. This time around he knew he would be the top of his classes and would definitely outshine the know-it-all Granger.
If things went according to his previous time-line, he hoped that it did, the troll would kill her. His smile, feral and terrifying.
The fifth is a fully loaded penthouse apartment. With a full kitchen, bathroom, study, bedroom and living room. It made the Dursley house pale in comparison. It is based off of the Potter Manor, which he had spent five years in trying to escape the wizarding world
The sixth is the command center, where he could keep an eye on all his enemies. And his friends, well his new friends. This time around when he saw the waste of space Weasley, he would send him packing. And when he saw that bushy-haired beaver teeth Granger, he would make most 7th year Slytherins pale in comparison. Malfoy may become a better acquaintance then enemy.
The seventh is a storage center for things that would take up space in his room. He would fill this too the brim with all the money, precious gems and metals he can conjure and make permanent. When he did get to Gringotts, he would empty his vaults out. He knew that the goblins wouldn't object because he would be giving them a new fortune to tend to. The Mort Peverell vault who be their biggest client and he would eventually adopt the name when he finally leaves Hogwarts.
The eight level is an outdoor terrain suitable for his exercises and outdoor training. For when it is raining, or snowing. Or if he just wanted to be alone, away from the toadying sycophants of the wizarding world. Or his foolish classmates who would not doubt try to befriend the boy-who-lived.
The ninth is the holding cells he would use for people who dared to cross him. Like captured Death Eaters and the Order of the flaming Turkey's as well. He would not differentiate from them. To him, they would not find him a eager to please puppet, but a wizard who would use his incredible wealth of knowledge against them
