“Yes, there are things to consider. A great amount of magic will be released at once, and it is imperative to keep the flow of it balanced and steady to ensure the integrity of the energetic structure. If there is a disruption, a phenomenon is bound to happen that we call a recoil, when all magic breaks out of the circle at once and wreaks havoc on its surroundings.”
That had happened many times over the course of Samuel Griffiths' career, especially towards the beginning of it. He had lived to tell the tale but was aware that the prospect of it might be frightening. It was the reason advanced transmutation had not been taught in practice in Hogwarts prior to his arrival. That was about to change.
“However, this shall not trouble us because I will not allow a full recoil to happen,” he assured her.
Stepping back towards the table, he said: “You see the runes that indicate where you place your hands. As soon as you do that and let your magic flow into the circle, you will feel it integrate into your field of awareness, like it becomes an extension of you. A quite remarkable sensation, really.”
He placed a piece of copper in the middle. This would be the material to transmute. It was pure and malleable, easy to control.
“Then you can attempt to change something about this piece of copper. You may find that you have a natural inclination towards a certain action. Most find it easiest to heat or cool the material, but maybe you will feel drawn to turn it liquid, alter the shape, or even transmute some of its properties. There is no way to know until you try. We have no goal right now, but to experiment.”
He looked up to her and felt a sense of anticipation. He was excited to see this. But first, he needed to do his due diligence to make sure she knew what she was getting into.
“Regarding the risk of a recoil; I will place my hands to the left and right side of yours, respectively, just outside of the circle. It is necessary that they are in light contact with yours so that I can connect and listen to the flow of magic without getting in your way, which would happen if I touch the lines directly. If I feel things becoming unstable, I will intervene and supply my own forces to balance everything out.” Meeting her eyes to make sure she understood the next point, he said:
“It is very important, whatever happens, that you do not break off your connection to the circle abruptly. When transmuting, we always have to sever supply to the circle in an orderly and controlled manner.”
He pulled back and removed everything from the table which they did not need, giving her some time and space to consider all of this.
“I want to assure you that there is no expectation on my side to achieve perfection on the first attempt. I certainly did not, when I started out. This is how I learned advanced transmutations as an apprentice, with my master safeguarding the process. I offer this to you because transmutation is one of the arts of magic that you can only truly understand the marvels of when you experience it.”
And it felt to him like she would value it, take something from this experiment that would take on its own life in her world.
The Homunculus appeared at their side, taking away their half-finished teacups.
“However, I understand if you would rather not attempt this. Take your time and let me know your decision.”
