"Finished."

"All right, Burgock. Hand me the contract."

Burgock flicked his fingers with an air of casual dismissal and with 'pop' sound, a parchment appeared in front of Sirius. "There you go, Mr. Black. All done."

Sirius leaned forward with anticipation. While it only took Burgock just around fifteen minutes to make the contract since his assistant, Odbert, fetched him the instructions, Sirius himself was almost bored to tears, so he was getting jittery having nothing to do but waiting for the Goblin to finish crafting it. He wished he had a book, or an actual person who would talk to him, or an actual wand on his person to keep himself fairly entertained, as the silence here was frightfully eery ― Azkaban was never quiet with all the echoing cries, soothing whimpers, and hoarse screams from his fellow prisoners. Sirius supposed he got used to background noises and here, deep within Gringotts' bank private room, there was no such thing.

Nodding gratefully to the Goblin, Sirius gingerly took it. The instant he touched the parchment, he felt wild Goblins' magic emitting from the contract. Soon thereafter, the contract drew upon his magic and, if he weren't mistaken, the magicks of his ancestors.

When that was over, Sirius exhaled out with relief. Once he was done inspecting the thick parchment, he took a quill that was just in his reach and dipped it into the inkwell. Carefully, he wrote down his magical name in the first column and Harry's in the column next to his. Then he stabbed the back of his hand with the quill (Goblin's quill was sharp like that), drawing blood. He smeared it over his signature on the parchment. The blood was absorbed into it and a swirl of air came from it and then it was done.

Sirius sagged in his seat while nursing his bleeding hand that was slowly healing because, duh, he's a competent Wizard, enough to heal himself without a wand (albeit the process was so slow, if it was a large, open wound, he would be dead before he even finished healing). This contract would bond them, him and Harry, for life. If Harry wanted to bond with another Witch or Wizard in the future, Sirius could simply just off himself to let Harry free of the bond. He was sure the Killing Curse could be cast and directed at oneself, especially if one had a huge amount of self-hatred.

"So, what will you do with your properties, Mr. Black?"

Sirius frowned. "We have discussed this. Seal all of them off."

"All of your family's properties, Mr. Black?" Burgock rolled his eyes at the blank face Sirius had. "Yes, you have so many properties all around the world courtesy of you being the last Black."

Sirius leaned back. He thought over it for a moment before he smiled.

"Ah, perfect. Grimmauld Place for the order it is, then." Sirius let his mirth at the idea show; his lips curled into a small playful smirk. He hadn't been to that house in years (maybe for almost twenty years), so he didn't know what state it was in. His mother was dead ten years ago, in 1985. Dumbledore had graciously informed him of that. "Seal them all but Grimmauld Place."

"Noted. Odbert will take you to your vault to collect the gold and the things you need."

Sirius absent-mindedly hummed, still over the moon about finally having the chance to protect Harry with the contract. Burgock coughed a few times, the sound effectively bringing Sirius out of his reverie.

"Oh, right." He straightened. "Sorry, um, kind of forgot that you suffered from bronze allergy, Burgock."

"I'm surprised you remembered that." Burgock gave him a mock of 'impressed look' and quietly snorted. "Go on, Mr. Black. Odbert's waiting with the cart to take you to your vault."

"Right. Thank you for your service today, Burgock. See you soon!" Sirius waved cherrily, indicating his good mood, before turning and skipping out the dimly-lit room. Once he exited, he cautiously approached the awaiting Goblin, Odbert, who was staring at him with expressionless face.

"Please jump in, Mr. Black." The Goblin gestured.

Sirius gingerly placed his hands on the edge of the cart and hopped into the Mine Cart.

"It's good to see you again, Odbert," Sirius greeted the young Goblin.

Odbert tipped his head. "Likewise, Mr. Black." He moved the cart.

It took forever, in Sirius' opinion, to reach one of the Goblins' deepest and most secure vaults. After they passed over vault number 711 (Sirius' personal vault), a few grumpy dragons, and then eventually they arrived to the the vault number 777, the House of Black's vault.

Odbert pressed his two palms on the entrance and there it was, a mountain of treasure waiting for Sirius. And so the first thing Sirius did upon entering was grabbing a bag with the Extra Extension Charm and Durable Charm added to it. He filled it with lots of galleons (knuts and sickles here and there too), books with titles that held his attention, trinkets that he deemed as 'safe', and many more. Then his feet brought him further back to the Blacks' Wand Collections.

Sirius specifically looked for the wand that would set his magic to react positively. It was luck, then, that he had found it immediately; a wand with the Horned Serpent's horn core and Yew wood made the magic around him tingle and like a bonus, it also radiated a sense of 'rightness'. The wand was made from powerful combinations that would even made Voldem ― the Dark Lord very green with envy. It belonged to his ancestor Caduceus, who was married to Medora of House of Gaunt.

Yes, unfortunately, it was a very Slytherin-like wand that Sirius almost hesitated on taking it. The key-word was almost as Sirius bent down and examined it eagerly anyway. It was costume-made for the House of Black's members only and even if he was underaged it would hold no trace just as his ancestors liked it.

He gingerly went to claim it and there it went, sparks and warm winds in his face emanating from the wand. A surge of acceptance and a sense of being embraced by the wand went through him, so Sirius was extremely convinced that this was the wand for him.

"Good Morgana, this is more than I had imagined having a wand once more. The best feeling. Ever." He regarded it like he had just met his long-lost friend and slipped it into the holster that was lying nearby. Strapping it on his hips, he turned to Odbert with a satisfied smile. "Let's get out of here."

They went on to the cart and when they reached to the hidden exit of the bank, Sirius deliberately paused.

Odbert knew what his client was waiting for and looked right at him. "We will inform Mr. Potter to come to Gringotts in two days, at dusk. Do remember that, Mr. Black."

Sirius gave him a wave and once he found some shadowy corner near the exit, he morphed into his animagus form and promptly left.
