Harry Potter: The Supreme Leader

Chapter 2

'CRUCIO!' the rat twitched madly, thrashing around for a whole minute.
Dark magic worked.
For the first two weeks of June, Harry kept himself in Number Four, Privet Drive.
For two weeks, Harry had trained himself.
Defense against the Darkest Art, The Darkest Art themselves, Charms, Transfiguration, History of both Muggles and Magic, Literature- almost totally Muggle because there was no comparable wizard equivalent, Runes, Occlumency and Legilimency, and of course... the Unforgivables.
And he has mastered two. Only Avada Kedavra remained.
Occlumency he learnt by the usage of thinking something boring, which blanked out his mind. Runes and flourishing Literature... 'Avada Kedavra.'

Vernon, Petunia and Dudley Dursley gazed at him hatefully.
He had threatened them, point- blank, that he would not be hesitant to use magic on them, because he could not be caught now. They were keeping out of his way...

'Boy! A bit of post came. ' Vernon Dursley handed him a letter. 'One of your freak letters!'
Harry raised his eyebrows. This was indeed serious...
To
Heir Harry James Potter,
May all enemies fall to your sword.
It has come to the knowledge of Gringotts Wizarding Bank that you have attained emancipation and that you are now a legal adult.
This is a request that you visit Gringotts at the earliest. Your properties and estates need to be discussed, and your lordships given. We have also discovered a few discrepancies in your vaults and we are extremely concerned about the fact.
Please visit Gringotts as early as possible. It is imperative that we discussed these matters of importance.
May your vaults fill with gold.
Ragnarok
King of Goblin Nation
Manager, Gringotts Wizarding Bank
Harry frowned as he looked at the letter. He had to visit Gringotts as fast as possible.
'I am going out for a while. I need to visit a couple of friends. I will not be back till the evening at least. They might come around asking where I am. Tell them I went to a friend. ' Harry told the Dursleys.
'Boy, ' sneered Vernon Dursley, 'how dare you order us around?!'
'I will hit you with a curse that will turn you into a pig...'
Vernon Dursley shrank and snarled: 'One day, you will meet a sticky end...'
Harry snorted and put on his best suit, before Apparating outside Privet Drive.
But he did not see the grizzled man who watched him...
