This is going to be interesting.
Usually, Servants are summoned through the Master’s words, which act as a conduit for the magic. But, well, it’s not like he has a voice to chant with anyway. As much as he had liked to use that excuse to get himself out of this last-minute mess he’d been dragged into, the Main Family had insisted he be the Master to represent their clan in the War. So he’ll just have to improvise.
Koe finishes writing the incantation along the lines of the summoning circle with an ink blend he had concocted himself: one that allows the maximum yield for magic output. While the voice is the most potent medium for casting, as had been proven to him by just how much the Other Side fear it, he has always been a proponent for the power of the written word. He places the catalyst the Main Family had given him—a golden pocketwatch they had gleaned from a previous war in a distant era—at the center of the circle before taking out a paper talisman he’d created and placing it between his lips.
Now is the time to prove to the clan, and to himself, that his muteness hasn’t rendered him completely void of use.
“From the Five, I incur,” Koe says in his mind and echoes with his mouth, though no sound emerges from his lips. “From the Thousands, I incur. Here, I declare.”
The five points of the Elements he had drawn outside of the circle glow, as do the first words he had transcribed onto the floor. So far, so good. Koe continues:
Let silver and steel be the essence.
Let stone and the archduke of contracts be the foundation.
Let the spirits of the other side be the ancestor.
Let a wall rise against the four winds to be felled.
Let the four cardinal gates close.
Let the three-forked road towards the Kingdom’s crown be turned.
Let it be filled—again, again, again, again, again.
Let my decree reach you now:
Your body will serve me.
My fate will rest on your might.
Thus is the oath I swear to you.
Should you submit to the beckoning of the Grail,
Should you submit to this will and reason,
Then come forth!
Light pours from the ink, and even the pocket watch, as the room is engulfed with a wave of energy. By the time the blinding magic had receded and Koe slowly peeked out from one eye, a figure had emerged from the circle. It worked, he thinks. But now that means it really has begun.
