Ragnok led Harry deeper into the Gringotts underbelly, boarding a secure cart that sped down a narrow rail. The wind howled in his ears as tunnels blurred past them—twisting, dipping, diving like a dragon mid-flight. Then they stopped suddenly in front of an enormous black door veined with glowing gold runes.

"Vault 394," Ragnok announced. "Potter Ancestral Vault. Active since 1014."

Harry stepped down onto the platform, heart pounding. Ragnok pressed a blood-crystal into a panel, and the door split open with a thundering hiss.

Inside: wealth, more than he had ever imagined.

Stacks of galleons in enchanted containment fields glittered in the low magical light. Crates of ancient artifacts, tomes bound in dragonhide, jeweled weapons, and shelves of heirloom items filled the cavernous vault.

Harry nearly dropped the parchment.

Ragnok smiled slightly. "Old money. Carefully managed."

Harry moved slowly through the vault, stopping to admire a gleaming sword mounted above a black velvet case. It wasn't the Sword of Gryffindor—but another ancient blade inscribed with runes.

"Peverell-forged," Ragnok said. "Your great-grandfather's ceremonial dueling sword. Enchanted to cut through minor shielding spells."

Harry nodded, taking in the feeling of history pressing around him like invisible armor. He turned. "Show me the next one."

Vault of the Blacks – Madness and Might
Vault 711 was darker, colder, and quieter. Its doors pulsed with Obscurus warding magic—malevolent and proud. As they opened, Harry could feel the legacy of a family forged in fire and shadow.

Inside: emerald flames danced across obsidian statues. Ancient tomes whispered curses as they passed. There were dark artifacts—some sealed in stasis fields—and heavily protected relics meant only for a Black.

"The Blacks were brilliant," Ragnok murmured. "Mad—but brilliant. You'll inherit it all when Sirius is exonerated."

Harry nodded grimly. "We'll make that happen."

Vault of Gryffindor – Relic of the Roaring Flame
The third vault was hidden deep beneath Gringotts—below the dragon pens, below the fire-chambers. The cart stopped before a gate covered in twisting runes of Old High Magic.

"Only blood can enter," Ragnok warned. "Few ever have."

Harry stepped forward. The gate hummed—then flared with gold fire and opened.

Inside was a single pedestal, upon which rested a red-gold ring and a book bound in lionhide.

The ring glowed as Harry approached. He slid it onto his right hand and gasped. A pulse of strength, old and noble, surged through his veins. The magic of Godric Gryffindor roared like a distant storm.

The book opened to a blank page and began to write in golden ink:
To the Heir of the Lion,
May your heart be strong,
Your wand swift,
And your vengeance true.

Harry stood there for a long moment.

Then he whispered, "I swear it will be."

Power Levels & Blood Magic – What the Documents Reveal
Back in the Hall of Heritage, Harry sat before a table stacked with magical documents. Ragnok placed one more scroll in front of him.

"Power Index, as requested. Measured via core strength, reaction speed, battle magic affinity, and legacy enchantments. The highest a person can get is 100. Merlin's 99, while Morgana's was 98."

Current top 15 most powerful wizards and witches (Gringotts Confidential – 1993)
Tom Marvolo Riddle (Voldemort)- 97
Albus Dumbledore- 96
Gellert Grindelwald- 95
Harry James Potter- 88 (Potential=93)
Sirius Orion Black- 91
Bellatrix Lestrange- 89
Minerva McGonagall- 87
Severus Snape- 86
Remus Lupin- 83
Fillius Flitwick- 81
Amelia Bones- 80
Kingsley Shacklebolt- 79
Alastor Mad Eye Moody- 76
Nymphadora Tonks- 73
Death Eater Average- 70
Average Witch/Wizard- 60- 65

Harry read the list, stunned. He was already stronger than McGonagall, Snape, and Bellatrix? And Draco… had outpaced Ron and Hermione?

"That's blood magic for you," Ragnok said. "Malfoys interbreed selectively. He's trained since he could hold a wand. His magic is stronger, but unstable."

Harry clenched his fist. "He'll be a problem."

"You'll be a bigger one," Ragnok replied. "Your core is still growing. The destruction of the Horcrux freed suppressed magic. Within two years, you'll reach your peak—and it will be legendary."

Legacy and Vengeance
Before he left, Ragnok handed Harry a sealed box.

"Left for you by Charlus Potter," he said. "Your great-grandfather. Contains the Storm Vow."

Inside: a slim black ring engraved with lightning bolts, and a scroll bound in silver ribbon.

Potter Clan Storm Vow
To the Last Son of the Potter Line,
When blood is spilled, vengeance must rise.
When innocence is broken, wrath must answer.
In fire, in shadow, in light—
You are the Storm.

Harry slipped the black ring on his left hand. The wind around him stirred. A crackle of raw, ancient magic danced across his skin.

"Let Voldemort come," he whispered. "I'll be ready."
