His Name Was Diagon
Hey, do you remember when I said we can trust Dumbledore for now?
"Uh," Harry perked up from his book. He'd been reading alone in the study room that Sirius showed him, and Geist had been silent for most of the day. It happened, sometimes - Geist could either be very talkative or almost fully tacit depending on his mood. "Yeah?"
I would appreciate it if we could both pretend I never said that. Actually, I'd like it even more if we could pretend I said something to the contrary.
Harry blinked. So you want me to not trust Dumbledore?
Precisely.
I'll consider it. Harry returned back to his reading; Geist, back to his brooding.
After dinner - which consisted of a classic and well-cooked beef wellington, roasted potatoes, baby carrots, Yorkshire pudding, crispy bacon slices over toasted bread, and fat sausages glazed in honey mustard; and for dessert, spotted dick with custard pie - Sirius and Harry engaged in conversation in the parlor.
"Tomorrow, after I'm done grading some of the summer homework my students sent me, I thought it'd be nice to go to Diagon Alley together," Sirius remarked. He moved his wand and cast a spell at the fireplace, igniting a flame on the ever-burning logs of wood. "And pick up some school supplies for your First Year."
"I, uh, sure," Harry mumbled, "What's Diagon Alley?"
"Oh, you'll see."
Oh, wait, Geist spoke up, Diagon Alley already? Damn.
"It's some magical place, right?"
Harry, this is pretty exciting! We're getting our first wand! Oh, it will be so great. I'll teach you how to circumvent the Trace. It'll be pretty damn great. I always loved spitting in the Ministry's eye and doing evil and illegal shit while it was busy wiping off the saliva, even when I was a kid. What a little hellion I was. Basically the Antichrist.
As Geist was beginning to use swear words and act like he was delirious - he did that sometimes - Harry elected to tune him out and ignore him, focusing more on Sirius.
"Ah, yes," Sirius chuckled, as he cast spells to tempt the fires to roar and expand slightly more, providing more warmth to the room. The fireplace and its mantelpiece were both covered in a thin script of runes. It had some pretty solid temperature and atmospheric enchantments on it, as Harry's research had uncovered. All of the fireplace's warmth was spread evenly across the room, and the output of the flames was modulated to ensure its brightness wouldn't leave spots in an observer's vision or irritate their eyes or nostrils. "Very much so. It's very much a hub for magical commerce and day-to-day affairs in London. Maybe the biggest one aside from the Ministry of Magic itself."
Hahahaha, Harry, we're going to steal so much shit. We're going to yoink so much shit. You're a thief now, Harry. A goddamn mugger. Gryffindor? Slytherin? Ravenclaw? Oh, ple-ase. Forget all that. You're a House Robber.
"Hmmm. Can I get a flying broom for my birthday?"
It's time for the sneakiest kid at Hogwarts to return in a full blaze of glory! Or, not, since that'd kill the stealth element rather completely.
Sirius blinked. "I didn't know you were interested in Quidditch. Actually, I don't recall telling you about it?"
Actually, hold on. Haven't you already learned the Unlocking Spell? We should practice on the Muggles in the neighborhood, then.
"I read books," Harry said.
Wait, no. You don't know how to Obliviate people yet. That's a terrible idea.
"How very Ravenclaw of you," Sirius snorted.
And I'm not even sure Obliviation is possible without a wand. I'm pretty sure the Unspeakables firm-ciphered that as well, and what a terrible shame. Actually, it's a stupid decision, too, when you think about it. It means a wizard without a wand can't really protect the Statute of Secrecy. God, I hate the Ministry.
"I'm not sure I'm cut out for Ravenclaw. I'd be more interested in making friends."
Forget what I said about Dumbledore. We're going to assassinate the Minister for Magic. As soon as you get your wand.
Sirius sat back with a smirk. "Hufflepuff, eh?"
---
A visit to Diagon Alley shall happen in the next chapter. However, before then, you must select your wand.
At the moment, you have 6.5 Gnosis - a relatively modest quantity. Save or spend, the choice is yours, but do be careful to not tread into debt, as that can have fatal consequences. Around a single Gnosis of debt can be procured without significant demerits, but to wander beyond that limit is to invite danger into your heart.
[ ] The Promised Wand [5 Gnosis] - A simple wand, nice and supple; eleven inches long, made of holly wood, and possessed of a phoenix feather core. An uncomplicated grip made from uncarved wood in the style of an ordinary tree. However, this wand seems to possess an extraordinary affinity for you...
"It is curious that you should be destined for this wand when its brother gave you that scar."
[ ] Design Your Own - A write-in option. Make your own wand by following the instructions below and making your own picks. As such, anyone voting for this option makes their choices by plan.
Wand Core
Unicorn Tail Hair - A core made from hairs pulled from the tail of a living unicorn. Doesn't operate well with the Dark Arts. A wand made with this core is more stable, with almost no chance of misfire or miscasting and mild results when it does happen. Also, spellcasting strength fluctuates less with caster's emotion. Geist doesn't recommend.
Dragon Heartstring - A core made from the heartstring of a dead dragon. Loves the Dark Arts. Somewhat prone to accidents. Unstable but powerful as fuck. Although this is common for all wands, this core remembers cast spells more consistently and helps them scale more.
Phoenix Feather - Made from a phoenix feather, self-explanatory. Has an independent, detached nature, doesn't care much what it's used for, and doesn't discriminate. Relatively stable, well-rounded, and versatile; neither stable nor unstable. Can sometimes act without you willing it.
Uncommon Core - Another type of core, such as Veela hair, Thestral tail hair, Troll wrist tendon, Rusalka nail clippings, etc. All of them generally make your wand more temperamental and unstable, hence why they are unpopular choices, but also offer their own unique benefits.
Affanc Hair [5 Gnosis] - An incredibly rare wand core; Ollivander remarks it's well-suited to wizards who have a pragmatic and straightforward personality. A loyal core, it yields and learns new magics easily, can be used for Dark Arts but doesn't particularly amplify them. It excels at protecting its bearer and fine manipulations.
Wand Length
Very Short - Around nine (9) to ten (10) inches. A perfect wand for subtle and precise effects, but doesn't have much raw oomph. A scalpel, rather than a hammer.
Short - Around ten (10) to eleven (11) inches. A wand that has excellent fine control, but not quite as much power as longer wands.
Average - A well-rounded wand; around eleven (11) to twelve (12) inches long.
Long - Around twelve (12) to thirteen (13) inches long. Has a lot more power to throw around, but might be less useful for fine and subtle utility.
Very Long - Around thirteen (13) to fourteen (14) inches long. It can pack a punch in every spell, but it's hopeless and clumsy at anything refined.
Even Longer - Around fourteen (14) to fifteen (15) inches long. Are you stupid? No one's used a wand this long since medieval times when blowing a door off its hinges was the only way to cast an "Unlocking Charm." Geist vetoes this choice. (-3 votes to any plan trying this.)
Wand Flexibility
Very Flexible - A wand destined for a wizard of an open mind who desires change. It's perfect for a jack-of-all-trades spellcaster who doesn't like to specialize too much.
Flexible - A wand that's well-matched for wizards who keep themselves unbolted. Good for those who want to be generalists with only a few, slight favorites.
Supple - A wand that lies in the middle of the spectrum. A decent selection if you'd like to specialize somewhat, but still keep some doors open.
Solid [1 Gnosis] - A wand for old people and political neoconservatives. It prefers one or two fields of magic to specialize in, but can handle other fields half-decently with some effort. Doesn't suit your personality and choices; Gnosis penalty applied.
Unbending [2 Gnosis] - A wand used solely by orthodox conservatives. Specializes in only one type of magic, sealed in after you begin to practice it more than another type. Doesn't suit your personality and choices; significant Gnosis penalty applied.
Wand Wood
Holly - A wood best suited for those with a tendency to anger and be impulsive. A wand made with this wood finds the benefits provided by its core to be especially potent.
English Oak - Embodies the British Isles, the druidic tradition, and old Anglo-Saxon ideals. A strong affinity with nature - useful for herbologists and frequent potioneers.
Hawthorn - A wood that works best with a wielder that's going through turmoil or conflict. Very loyal. Adept at both preventing and inflicting harm.
Vine - A wood that resonates with those who seek a higher calling or purpose; fanatics or visionaries. It can produce magical effects simply via proximity, without active input.
Sycamore - A wood strongly associated with learning, it bends to those who learn new things, and is especially effective at mastering new effects. Hates complacency.
Cedar - A wood that works best for those who have a sense of loyalty. It can't produce a miscast or hurt a friend.
Aspen - A wood that prefers wielders of exceptional willpower and determination. It's generally useful for all manner of defense against the Dark Arts and similar tasks.
Alder - A wood that prefers helpful and considerate wizards or witches. It makes non-verbal casting of even relatively advanced spells into an easy task.
Ancient Roman Wand Wood [7 Gnosis] - How mysterious. Ollivander mentions the wand made from this wood is one of the last such in the world, but he's willing to sell it to you for pennies because you're the Boy-Who-Lived. It must be pretty powerful.
Write-in - Any kind of wood in the world, literally. A comprehensive list may be found on the Harry Potter Wikia. Make sure its personality aspects fit Harry's established traits or a penalty may be applied - in some circumstances, the wood pick might even be vetoed by the QM.
