Diagon Alley was thankfully empty of people when they arrived. It was too early for most shoppers and thus he would be able to sneak Gellert into his shop unseen. They really did not need someone recognizing him and reporting them to the aurors. Still he didn't take any chances and ushered the former Dark Lord towards his shop.

At the door to his shop Harrison felt his wards flare and testing their magic and intent. It accepted him fully but only tentatively accepted Gellert. He pressed his left hand into the door and it unlocked. Right as it did so he felt a second set of spells wash over him. They were not spells he had laid out on his shop and made his skin crawl in disgust.

Harrison drew his hand back just as it released him and disappeared. Fuck fuck fuckity fuck. He had a pretty good idea of who ordered that magic to be placed on his door. It was too unfamiliar to be the man himself.

Riddle truly did not know when to give it up. It wasn't like he didn't know this from all the times he faced off against Voldemort. But still it annoyed him to no end that he was still having to deal with it. Especially since he just got back from Nightingale.

Gellert gave him a concerned look but he didn't say anything. Instead opened the door and ushered him inside. The store was exactly as he left it. If smelling musty from being closed up for all the time he was gone. He fired off spells to lock and secure the door as well as alert him if someone tried to enter.

"A little paranoid much?" Questioned Gellert with a raised eyebrow.

"I have a stalker," he growled out, "One who cannot take no for an answer."

Gellert made an amused sound but didn't say anything else. Instead he took a good look around the shop. Once Harrison was satisfied the shop was secure he headed for the backroom. In there he hit the lights and the ward that would stop others from sensing the magic that happened inside. Then approached the trunk on the floor. Gellert was right behind him and at a look he closed the door sealing them inside.

Harrison pressed the buttons on it with practiced ease and a little wariness knowing his notes were there. In the top part of the trunk were his essentials for work. Under that were a few different books on Runes and spacial magic. Each were set aside as he looked for the parchment.

Finally he pulled it out just as Gellert entered the room. As curious as ever the man asked, "What is that?"

Harrison answered truthfully, "It was the spell I was trying to cast when I was back in time. A Grade Five Military Level Magic Spell."

"Blessed Mother," breathed the Dark Lord in surprise with just a hint of admiration.

Harrison unrolled the parchment. It didn't look much like on the outside but as soon as it began to unroll the real length was revealed. It held all of his notes from years worth of work. The different magical circles he had tried. All the runes he used.

In looking at his final set of rune sequences he caught the slightest mistake. One that completely ruined the sequence and he was lucky it hadn't killed him. Harrison felt it click within him and he pulled out his Master CAD. To most it would appear to be made out of simple steel. Miniscule writing was etched into the steel however.

Pulling his magic from his core and down his arm into the CAD. Almost immediately the room became alight with the magic circles he had put into the steel. The etchings allowed him to call them forward and edit them as needed. When they were settled and working as he wanted he would be able to inscribe them into an Intermediate CAD.

Gellert asked his eyes scanning the spells, "Harrison what are you doing? These are high level spell and will bring aurors down upon us."

"No they won't," Harrison replied as he used his magic to change the mistake, "I have wards up that will protect this place from being sensed by anyone on the outside. Well except maybe by you, Dumbledore, and Riddle."

They were the only ones who might be able to sense it. But only if they were right on top of the shop. He had done nothing to draw Dumbledore's attention thankfully. The only one who could possibly sense it was Riddle. He had to know however. He had to know if his spell would work or if it would send him home.

...

Gellert stood froze as he watched the young man in stunned silence. The air around them grew hot and heavy with the elemental magic. He could practically taste the darkness on it. This was different from any other spells Gellert had seen Harrison use before.

Sure the young man wasn't a Light Wizard, the spells he used put him firmly in the Dark even if he was Light Minded but this. This was something else entirely. Gellert did not think he would be able to move even if he wanted to at this point. His self preservation instinct would not allow him to.

In front of the young man the other magic circles disappeared one by one. Until there was a singular five layered spell in front of him. There was a mixture of familiar and unfamiliar runes within it. It reminded him of the reason that Technomages like this man needed a Runic Mastery. Few would have the patience much less the skill to be able to combine runic sequences of different languages.

"I am he who slays and captures gods," came Harrison's voice.

It was deeper than he remembered with his eyes flashing brighter with power. A dark of condensed magic began to form around their feet. Sparks of orange occasionally shot around in the mist. Gellert wondered if this was going to be the end of him. The sheer amount of power he felt was unlike anything he had felt before. He had severely underestimated just how strong Harrison was.

When he had locked in Harrison's magic before he thought that had been all of it. It wasnt anything to scoff at don't get him wrong but it wasn't what he thought an elemental should be at. This was something in a league all on its own and Gellert for the first time wondered if he was in over his head.

"I am the one who knows the end and the founder of genesis. / Return thyself to the cycle of providence, / The five elements to elements."

Gellert bit back a yelp as the orange in the mist shot out and hit him in the gut. The area burned like hellfire but he dared not interrupt the spellcasting. That would be utter suicide and he knew it.

"And sever the links woven between images and truth. / Now all of creation shall perish here, / At the distant ends of the void. Black Magic: Extinction Ray!"

A pillar of golden light came from the five. It hit the far wall with such strength he thought it would cause the building to collapse in on them. The entire building shook with it's force and he wouldn't be surprised if it was visible on the outside.

After a few moments the pillar disappeared along with the mist. For a moment they just stood there. Harrison was looking at the wall with an unreadable look. It almost seemed... resigned. Like he had expected something else to happen.

Gellert reached out to Harrison uncertain if he would welcome. He was ignored though green eyes were no longer blazing with power. They had dulled out and he was unsure of what he should do.
