Harry was all confused. In all his 10 years no one ever wrote to him. Nor any family member tried contacting him. He was all confused. And now this letter. "Who would be writing to a freak like me? Whoever wrote this where were they for all these years? Why are they writing all of a sudden? What do they mean 'not responded to previous letters? What the hell is gringotts?" All these thoughts were gushing through his mind.
As Harry went through the letter again without realizing he said Gringotts aloud. Sitting on the swing the next thing he realized that he was fell on something hard. When he looked up he got scared. He saw strange looking creature sitting on a high stool behind a large counter, scribbling in a large ledger. When he was about to ask them the creature looked down at him(he was on a stool and Harry on the floor so the creature had to look down) and said "Who are you human child? And how did you come in? "
Harry replied by saying, "I was reading the letter brought to me by an owl and as soon as I said gringotts I was here. Where am I? And what… I mean who are you? "(Harry said all this so quickly that the creature was amazed that he did not fall short of breath)
The creature responded saying that he is a goblin and works in the bank of the wizarding world. All Harry replied was, "there is no such thing as magic". In response the goblin asked him his name. "Harry Potter" The goblin took a double look at him and then the scar on his head. The goblin took out a parchment'and a knife. It said to Harry, "Mr. Potter put two drops of your blood on this parchment'. If your who you claim to be then you will not be punished or else you will be beheaded." Harry was now trembling with fear but did as he was said. After a minute or so there was writing on the parchment

After reading this the goblin got very angry. Harry was bewildered. The goblin then looked at him and asked him to sit down. The goblin told him everything. From the day he was born to the day how he defeated Voldemort. Harry asked the goblin who he was and the goblin smiled(if the goblins can smile) and said that he was the head of the goblin state and he owed the Potter Family and vowed to help Harry in every possible way he could.
