Scathatch watched on as Sirius left the Pit after a year of staying in. Every monster that tried to attack him was skewed by a reinforced rock spear through the throat with pinpoint precision.
That's when he succeeded in the goal of going into the Pit. Using all the tools at your disposal in tandem with one another. Before Sirius would take time to mold his alchemical spells with his reinforcement, now he was using reinforced alchemy at this point.
However he still looked unhappy at the progress he had achieved from Scathatchs point of view. She couldn't read his mind to know that he couldn't replicate the monsters movement of souls even a little bit.
This put his plans for alchemical transfiguration on hold for a bit until he could figure out how to make his permanent energy source, as even his magic core wasn't enough to transfigure some of the more 'grounded' things.
"I see you have had quite the transformation....." Scathatch muttered as Sirius stood in front of her with his beat up clothes and cracked sword. The Sirius from a year ago could wipe the floor with her holding back as much as she did back then and then some.
All he needed now was to learn rune magecraft and sharpen his swordsmanship. She turned to his automail arm. "I see you have changed the form of your arm."
His arm was now thicker almost twice the size of his other arm. Sirius nodded along with her words. "The only problem I have with this new configuration is that it messes up my balance as I have a lot of weight concentrated on one side."
"Then why keep it?"
"It's a battery that is used for one of my specialized magecraft." Scathatch nodded and took him back to the castle.
...
"Lets see how far you've come....."
As they were walking Scathatch turned and thrusted her spear right at Sirius's chest. Sirius merely deflected the blow back at Scathatch, who easily stopped her attack.
She spun her spear and slashed at Sirius, meeting his sword that broke on impact. But the broken sword released a shockwave that sent the two flying in opposite directions. When she was about to run to Sirius, she found him standing right in front of her, a newly created sword seen in his hands.
Scathatch scanned him up and down happy with the improvements he made physically. Right as she was about to cast a rune spell to cut him, Sirius retaliated. All it took was a finger snap and his automail arm glowed as the very air turned into metal chains, restraining Scathatch.
"Umu, very good pup. Looks like the Pit succeeded in what I wanted to happen." She disappeared and reappeared on her throne, her posture was strong. Sirius on the other hand opened some vents on his automail arm and smoke billowed out.
Then the battery in the arm dimmed just a bit. Proving that the battery wasn't only going to last very long as the transfiguration spell he used wasn't very energy consuming. If he were to build like another body then that would be way over the limit.
"You will next look into magecraft, more specifically rune magecraft. Once I deem you worthy to inherit them, I will implant them into you. It will help you tremendously with your alchemical magecraft." Sirius nodded.
They walked through the halls until they reached a library. The room was filled to the brim with notes and books, all of Celtic origin, each one was written by Scathatch or someone Scathatch deemed worthy.
In the middle of it all sat a magic circle that was outlined with runes.
"Come. You and I will sit in this runic circle as I incant each of my runes. You will understand them as I incant and relay their effects. With this, the process of gifting my rune magecraft to you will be complete."
Once they sat down the circle lit up and mana funneled into the two as Scathatch casted her runes allowing Sirius to feel them and try to understand them. Of course Sirius may be smart, sometimes, but runes were a whole other matter.
The rune magecraft was made by Odin the King of the Aesir. His runes were on the level of the Greeks divine words. What made them so versatile was the fact that you could combo them and use them in smithing, like how Scathatch made Gae Bolg.
'I can feel them.' He watched as his master muttered another rune and the wind picked up around them. Right now he was a little over a year into his training and he had already become stronger in swordsmanship alone against someone like Artoria with Excalibur equipped, of course the Excalibur with thirteen seals on it. He wasn't that strong just yet.

Camelot
With her witchcraft Morgan could easily locate the feeling of despair and disgust spread around Great Britain, after a year of looking. But the thing she found gave her a feeling of terror, not something she was expecting.
However, she could use this.
She nodded at that thought and made a plan. A plan to rid the world of a certain magician and Mother Fairy. She was a witch queen, of course she knew about Sirius's true magic, Merlin found out after looking deeply into Sirius's hole in reality that seemed to surround him at all times.
'I just need to manipulate Vivian. After all, no one knows her better than me~' She laughed as she disappeared in a smog of darkness, her laughter echoing into a chamber where a little girl with blond hair sat.
'What the fuck does that witch want now?!' Her blond hair was scraggly and her body had a fresh set on markings from the recent lashing she received. Then she cried herself to sleep at the stress of her torture and her loneliness.
'Help.....someone.....anyone....help me.....'
...
"Sigh....the things I do for humans." The white haired magus sighed at the sight of Morgan laughing manically. He saw everything, he heard everything, and he knows about everything happening presently.
The only things known to have escaped his sight are beings of higher power or Sirius's entrance into the world. Though after making his mark on the world, Sirius became visible to Merlin albeit on a limited level like looking through a dense fog.
'If I want humanity to survive and thrive I must let the mystery die out. That means Morgan, Vivian, Artoria, and Sirius have to go.' He noted and planned for each down fall of each person, regardless if they were close to him or not. After all, the only thing that matters in the end is humanity.
