HP: In The Magical World As An Extra

The small goblin stopped his scribbling and looked down at me with a raised eyebrow, "A young wizard with manners? Now this is a rare sight. What business does a child have with Gringotts bank, and be quick, less my sword find your throat. Time is gold." he spoke with an amused yet annoyed voice, likely trying to scare me, it didn't work.

I held up my letter to the goblin, "I was told to come to Gringotts to get my school funds to buy my supplies for Hogwarts, I was hoping you could help me." I stated plainly my voice solid.

The goblin took my letter giving me a curious look, likely because of my not reacting to his threat, and read through it quickly he nodded, "I see, very well, you will need to undergo an inherency test first, to check that you are indeed legible for the funds. If you have magical relatives they or your house would be required to pay for your schooling." he said as he waved his hand to another goblin who came over.

I heard them speak in some kind of language which I remembered was called goblin speak from the Wiki and before my letter was handed back to me, "This goblin will show you to a meeting room where you shall have your blood tested. If you are not part of any house you shall be given the key to a Hogwarts student vault with your funds inside." he said in dismissal.

I nodded and turned to follow the goblin who lead me to a set of double doors where I was lead inside, "Wait here" the goblin said gruffly before leaving.

Looking around the room I could see there was decorated rather nicely, though it could do with a clean.

There was a solid wood desk and two chairs in the middle of the room where I assumed I was to wait and so sat down in the chair facing the door to wait to be met.

After a minute or so the doors opened and a goblin came in pulling a large wooden box on wheels, he looked to me before grinning, "Are you the to-be-student, who's here for an inherency test?" he asked.

I nodded my head stiffly, "I am." I replied as I watched the goblin approach the desk before stopping to open the wooden box and taking out a stone bowl that had a number of carved runes on its rim with a red ruby in its centre, and a curved knife with similar runes.

"I need your blood boy." the goblin said with a grin as he sat at the desk and placed the bowl in front of me.

I looked at the bowl before speaking, "How much do you need for the test?" I asked straight.

That seemed to take the goblin back for a moment at my unflinching, it would appear some of the fanfictions were right, goblins did like to make wizards squirm. Well I must have been a bit of a shock for them.

Shaking the shock off, the goblin cleared his throat, "Five drops will be sufficient," he said before handing me the knife.

I nodded back taking the knife and pressing the tip to the tip of my index finger and pressing hard enough to break the skin before holding it over the bowl and letting five drops fall in before taking my hand away.

I watch on with slight awe as I watched the cut close up as the same time as the runes on the blade glowed. So that's what they were for. I handing the knife back to the goblin.

As the goblin took the bowl back I watched on as he tapped the runes in a sequence as they light up and my blood was soaked into the ruby in the centre of the bowl.

Seconds before a thick black smoke started to poor out of it, floating up and forming a shield.

My eyes widened as I recognised it from the wiki, I had seen it a number of times and I couldn't believe what I was seeing.

It was a shield divided into two, the top half with an armoured arm holding a sword and the bottom part with three birds, ravens or crows, I felt my mouth open seeing it before I looked at the goblin who looked to be just as shocked as I before he cleared his throat.

"Well this is most surprising, it would appear child that you are a lost son of the Most Ancient and Most Noble House of Black." the goblin spoke as I looked back up at the crest as it faded away.

I was a Black, like Sirius, but…. But… "How?" I asked openly not understanding how this could be, I knew that Sirius didn't have any kids, unless he did and I was him. I just couldn't think how else this would be possible.

The goblin grinned, "Let's find out, shall we," he said as he moved to the box and took out a quill and a sheet of parchment.

"I will need some more of your blood," the goblin explained handing the bowl and knife back to me, "ten drops this time. Once it's done I will use the quill to trace back your magical family lines for three generations on either family side. After that I'm required to hand you over to your families account manager, I believe he will have a number of things to discuss with you now that you have been identified as a son of the House of Black."

I nodded taking the knife and once again cutting my finger and giving the required blood into the bowl. The same thing happened as before as I watched the cut on my finger heal before I passed the bowl over.
