Chapter 1: Home is Where the Dursleys Aren't
...
Harry inflated his aunt, smuggled himself to Diagon Ally, and got something akin to a pardon from the Minister.
The next day he needed money for school shopping. He went to Gringotts, but didn't have his key, so things... diverged a bit.
When he took a blood test to check his identity the goblin, Axegrinder, uttered on single mildly annoyed word in gobbledygook and looked up. "You have a claim to the Potter trust vault, and the vault of Jered Jones. You have already claimed the first, would you like to claim the second?"
Harry stared for a second, waiting for his brain to restart, before asking, "Won't Mr. Jones mind?"
The goblin snorted, "It says quite clearly in his will that the first magical male descendant to make a claim after a verified blood-test would get his vault and everything in it. He paid for a five hundred year lease for that, and he only died in 1683, without magical children or grandchildren. As far as we are aware, you are his first male decedent to have a blood-test here. Would you like to claim the vault?"
Harry shrugged, "Sure, I don't see why not."
"Very well, here are your keys. After inspecting both vaults you can combine them, though you may want to wait until you are of age since the Jones vault has a higher withdrawal cap. Shingouger! Show him to his vaults!"
After a ride on the cart, they came to the unfamiliar vault, it was unremarkable. Completely ordinary as far as Gringotts goes. He unlocked it and found... a large pile of very strange coins: gold, silver, and copper, multiple types of coin for each material. He looked closer, but couldn't recognize any, until he got to the florin... he'd never seen a real one before, they were so old, but he'd seen a picture.
He looked at the Goblin, "I have a treasure trove of collectible coins, don't I?"
Shingouger shrugged, "Wizarding world didn't get it's own currency until the statute of secrecy. This vault is old enough to have different coins. You want to keep 'em, or exchange 'em?"
Harry thought for a bit and decided, "Can I keep twenty of each type of coin? I'd like to keep some, but I don't need to keep them all. I also don't need it quickly, so... sell the rest to the highest bidder?"
"Alright, you gonna go in the artifact section?"
"What artifact section?"
The Goblin rolled his eyes, "There's a door behind the pile of coins."
Harry looked behind the coins and, sure enough, there was a stone door. He opened it and went inside. There wasn't much here. A few chests, mostly full of papers. When he opened the last dust covered chest, he heard a thunk. He looked behind the chest, and saw a envelope. He opened it.
Inside were two rings, what looked like a couple deeds, and a letter.
Dear Great-Grandson,
Congratulations! You have some money, my notes, a house, and an island in the New World. You may need to do some fixing up, but the amount of money I spent on enchantments and bribes should mean there are no legal squabbles. Anti-bureaucracy wards are very expensive, but any required documents will file themselves automatically, and no bureaucrat can meddle with the documents without your permission. It keeps people out of your business while simultaneously cutting back on the dreaded evil that is paperwork.
There are some unique magic creatures on the island. If anyone asks they were there when I found them. There are two types. They are called Bloops, and Crumple Horned Snorkacks. There are details on them in my notes.
The rings are mega-portkeys. If you tap the gem with your wand, you will teleported to It's designated point. The red goes to the London townhouse, the green takes you to the island. Each can be used once a day, so it has time to recharge. You can have a maximum of four average sized passengers. This keeps people from trying to use your island to host parties you'd rather not have anything to do with.
Sincerely,
Jered Jones
He had a home. His own home. Two of them. One was an island. He smiled. He'd need some do it yourself books.
