As soon as he arrived he went to the floo chimney in a hidden part of kings cross station and chanted "diagon alley".
He was enveloped in green flames and vanished.
Diagon alley was decorated with all sorts of christmas decoration. A few fir trees stood on the side adorned with fairy lights.
It was a truly unique sight. Before he went to Gringotts he bought a few christmas gifts for his friends. A few sweets for everyone together with a coupon at Olivanders for Neville and a Nimbus 2000 for his brother.
He also added an explanation for Neville stating that his wand didn't fit him and this is the reason he is so bad at magic.
When he was done he put everything inside his ring and went to Gringotts.
Of course no one would sell a house elf to a child no matter how much money they had so he took out his clowns mask and transformed himself into a man in his twenties with green eyes and curly black hair.
His face also had aristrocratic traits with his high cheekbones and thin lips.
Without hesitation he entered Gringotts and strode to the section where house elves were sold.
"Hello, how can I help you?" the goblin asked with an expectant gaze filled with greed.
"I need a young house elf who is good with magic and is quite smart. Just name your price" he said confidently.
"If you would follow me good Sir..."the goblin said and led him to the elf quaters.
There were hundreds of elves in the big room and doing work. They all wore robes in defferent colours. Some red, blue, yellow, brown and so on.
"All lilac elves to me!" the goblin shouted and three elves rushed to him. It seems these elves were quite rare.
"Just pick one good sir. One is as good as the other" the goblin said.
"I'll take all three" Orion just said. It was perfect. One elf for him and his brother and one elf to keep Camelot in shape.
"Excuse me? Sir I am afraid these elves are quite expensive..." the goblin said.
"Just name your price, money is not an issue" Orion just said.
"500,000 Galleons Sir no bargain" the goblin said.
Orion just nodded and pulled out a small mountain of galleons out of his ring.
"Exactly 500,000 Galleons. Pleasure to make buisness with you" Orion said and turned to the house elves.
"Your name will be Deek, yours Rosa and yours Flik" Orion said and put a hand on their heads as he performed the bonding ritual while giving them names.
"Well then goodbye" Orion said to the goblin and said to one of the house elves "to the forest near Preston" and all four dissapeared with a pop.
He reappeared in the same old forest he woke up after the failed ritual. It then took a while until he found the ruins of the castle.
Changing into his normal appearance he took off his clowns mask and put it inside his ring.
"Alright, we are here. Our task for this week is to rebuilt Camelot" Orion said and ignored the confused gazes of the elves.
With a flick of his hand all trees were unrooted and thrown aside. The soil on the ground parted and showed the stone floors of the old castle. But he also felt his magic rapidly declining.
"This isnt going to work like this..." Ofion muttered as he saw his pitfull progress.
He then took out a rune stone and began drawing cursed runes on it.
It was his plan to set up a magical array that used the magical energy of the surroundings to reconstruct Camelot.
After a whole day he finished inscribing the rune stone and felt how all magic was sucked into the stone which began to glow and gloat in the air.
Orion just slumped to the ground and watched as the surroundings slowly changed and parts of the castle got repaired. Of course it was a very slow progress but he expected that the array will complete the reconstruction in around a month.
He just sighed. Without the magical leyline active Camelot was just a normal castle.
He got up and went to the deeper parts of the castle where the gault and the dungeons are.
"Alright everyone... we need to clear out and repair these corridors" he said while pointing at the mountain of stones in front of him.
The elves just nodded and went to work. After three days of constant work they finally reached the chamber with the magic core of camelot.
Orion just looked at the wrecked pieces of the magical reactor and sighed.
"This is going to be a lot of work" he mumured and got to work.
All the enchantments have fallen apart and the leyline was blocked by rubble.
With a flick of his hand he vanished the ruble and felt the leyline slowly returning to life.
After two days he was also finally finished with reconstructing the magical reactor. Of course it was a far cry from the original but the magical density would at least be four times as good as in Hogwarts.
The reconstruction also sped up at a visible speed as the array was provided with mord mana from the repaired leyline.
"Good work everyone, now we just need to wait until it is complete. Rosa, you will be in charge of this castle and the secret keeper of the fidelus charm" Orion said.
Rosa bowed deeply with tears in her eyes "it is my greatest honour Sir".
Orion then began chanting the Fidelus which enclosed the whole area around the ruin. A light floated into the head of Rosa and the charm was completed.
Orion felt how all knowlege about Camelot vanished from his mind and the half completed castle in font of him returned to a normal forest.
"Camelot is here" Rosa said and the castle reappeared.
"Amazing" Orion said fascinated then returned his attention to the elves "I'll be away for a bit. Your task is to restore the library and furnish the castle. The money you need for that is in the treasury. As house elves you have full access. Make it as awesome as you can. I'll be back" Orion said and apparated away.
He reappeared in a militairy post in the outskirts of London. With a notice me not charm he searched the whole army and soon found the locked room where most weapons are kept.
'Seems like I don't even need the Imperio curse' he thought and pointed his hand at the locked door.
With a few clicks the door opened and Orion finally saw his new weapons.
From normal police-pistols to heavy rocket launchers and sniper rifles.
Orion just shrugged and put everything inside his ring while he had a mad grin on his face "hehehe".
When he was finished looting the whole room he dissapeared with a quiet pop and reappeared at Camelot.
He unloaded everything inside an already finished room and organized everything. He would mostly use the machine gun and the sniper so he should start by optimizing them first.
When he finishes setting up his weapon room he placed the other vanishing cabinett in the corner of the room.
Today was the day before christmas.
