Harry spent a few moments basking in his new old body. The cramped space of his cupboard wrapped around him like an old friend, the kind you tolerate having a once-a-year drink with, but who soon reminds you why you stopped being their friend.
Right! Time to fly this joint. Prison break! And with a loud crack, the cupboard under the stairs was empty. The Dursleys could fix their own damn breakfast.
He appeared in a park not far from Privet Drive and sat down on a bench. The sky slowly brightened as the sun rose over the nearby trees, flooding the grass with light that refracted off morning dew and painted a picture of peace and happiness in the back of Harry's cornea. Freedom.
Harry would never again let anyone imprison him. Not Voldemort, not Dumbledore, not the Dursleys, not his parents.
To do that he needed power, for without power you were helpless, and if you were helpless everything you have can and will be taken from you.
So, what did he have?
Well, he could do a limited amount of wandless magic. He could summon and banish, apparate, fly, talk to snakes, cast the stinging hex, lumos charm, and incendio charm, as well as basic legilimency and master occlumency. Wandless magic was time consuming to learn and Voldemort had never learnt more than the combat critical necessities.
His ring would protect him from obliviation, mind-altering potions, confundus charms, and other mind altering magics… but not the imperius, nothing could block the imperius — you just had to have the mental will to throw it, which is why it was classified as unforgivable — poor little pureblood lords couldn't defend their families against it. The ring could also become visible and invisible on command and was soul bound, meaning it couldn't be taken from him by force until he died.
All this was very nice, but it didn't make him the all-powerful force of nature he needed to be. Wards could easily block apparition, and his combat spells were very limited. If he got in any trouble in the magical world, he'd be at the mercy of whatever wand wielding weakling with a basic OWL in defence stumbled on him. Worse, he had almost no sneaking abilities. Disillusionment, notice-me-nots, muggle repelling wards, key-in wards, silencing charms — as he was at the moment, he couldn't do any of them.
He needed a wand. Then his repertoire would be vast. Then he could really get on with things… but… how was he going to get one? Ollivander and his British contemporaries wouldn't sell him a wand, he was too young and the wand would have the trace on it. Other countries also wouldn't be any good — they'd still apply the trace, and it would just switch over to Magical Britain the moment he crossed the border. The ministry would be very interested in why there was an unregistered underage wand casting magic all over the place. He could get a wand without the trace if he revealed his status as Lord Slytherin, but he wasn't anywhere near ready to announce that yet. He could try stealing one, but that would be far too risky at the moment. If he were caught he'd be in big trouble.
No, there was really only one option. He was going to have to make one.
It wouldn't be great. It wouldn't be at the level of perfection of one produced by Ollivander, but it would work and be functional until he could buy a proper one. And since it was the wand that chose the wizard, or so Ollivander would say… well… he'd just have to think like a wand.
…Yew. Yes, the wood of death and rebirth, of resurrection and immortality. Voldemort's wand was yew because of its properties associated with eternal life—although how the wand knew of the Dark Lord's future when he'd been just eleven was anyone's guess. His wand, by contrast, would be yew because of its properties associated with rebirth and resurrection, not to mention he was Death's champion.
And for the core… thestral tail hair, definitely. No creature was more closely associated with death than the thestral, except maybe the grim. As for the length… 15 inches, the same length as the elder wand. The wand made by Death. Yes.
Harry leapt off the bench and stretched his arms to the heavens. Shopping time!
