Merces

"As dragon blood runs within my veins, I can easily control these flames."

Meh. Could've done a lot better with Caster herself instead of ripping off an already-established design, but... I was lazy. :/ And as usual, I fail in blending the character with the background. This is just randomness. I won't be as lazy with the designs of other six five Servants. itsnotliketheresanythingformetoripoffanyway.

----------------------------

“Tohya Tohsaka is definitely a participant.” A man muttered, sitting on top of a high rooftop.

His name was Adam Stone, having come all the way from England to participate in the Third Heaven's Feel.

Caster stood nearby, silently gazing outside the warehouse window. He had been silent this way ever since he had been summoned. He hadn’t asked the man’s identity, hadn’t asked if he was his Master. Compared to an ordinary Heroic Spirit, Caster’s behavior was abnormal. He ignored his Master’s words.

“Other definite participants would be magi from the Einzbern and Matou families...” He mused. “And perhaps the Edelfelts might be participating too.”

He looked over to his Servant, who was still quiet. He wore a red overcoat lined with polished black paint at its edges, and over this a heavy gray armor consisting of gauntlets, chestplate, pauldrons, greaves and a horned helmet that masked his face. On the chestplate was a strange symbol with an uncanny resemblance to Command Seals. He was completely unidentifiable.

Who was this character exactly?

And why was a Caster-class heavily clad in armor like a knight?

“After all my efforts, this world is still locked in war...” Caster muttered in a tone that implied exhaustion, the first words he had spoke since his summoning. He had a strangely feminine voice, though it was muffled by the helmet.

Adam continued to observe this supposed hero. With his colors and design, he looked menacing, more like an overlord from ancient times than somebody belonging in the Throne of Heroes.

“If I may ask, what is . . . underneath that helmet?” Adam asked, a little hesitantly. He didn't know if the Servant would reply.

“…This?” The clad hero took hold of the helmet covering his head. “It was once a symbol of mine...but I do believe I have no further use for it.”

And with that, he pulled it off, before letting it fall to the wooden floor. Its weight was unexpected; the helmet completely broke through the wooden floor and half-buried itself into the earth below, emphasizing the strength of this Heroic Spirit.

But what really intrigued Adam was his face. It was slim and lithe, with fair skin, blonde hair, and green eyes. At this point, he couldn’t tell whether this magical knight was a 'man' with a pretty face or a 'woman' with a masculine strength and armor. With that, his young and vivacious head made it hard to believe that he was a Heroic Spirit.

“Who . . . . are you . . . ?” He asked, dazed.

For a moment, the figure gazed directly at Adam himself. His eyes were quiet, but they had an undeniable flame burning behind them. A flame that had seen far more than ordinary humans, as if he had participated in over a thousand battles...

“I will not tell you so easily. But consider that your summoning ritual ended up flawed.” Caster replied, before he turned to the door. “.…hm. Shall we step outside?”

...What?

Adam was confused by this request, but obeyed anyway. He ignored his implication that something might've gone wrong during the summoning ritual. Of course not. The duo walked out the warehouse, and as they did, Caster held up his two arms into the air. He remained that way for a short while.

"I can sense you do not trust my abilities." He told his Master. "You have no use for this warehouse, correct? Therefore, I will display my power - as a Caster."

Right then, a circle of flame began to surround Caster, and his arms slowly began to drop down from the air. As they dropped, the warehouse began to catch fire - and this fire spread remarkably, quickly engulfing the whole structure of wood before ten seconds had passed. Adam silently watched the warehouse burn. It was true that he had no use for it. It wasn't even his.

Then he began to notice that there were strange properties within the flames. He caught on quickly. These flames were entirely composed of prana. Normally, such a feat was impossible. Only the flames from the breath of a dragon had such properties, otherwise it would only be an illusion.

But there was no doubt. This was real. The smoke, the smell, the heat, everything was real. So how...?

"This dragon fire was summoned from my Reality Marble." Caster explained. "As dragon blood runs within my veins, I can easily control these flames. It is no large feat for me to control their size and radius."

Then he snapped his fingers and the flames immediately scattered, returning back to the Reality Marble contained within his mind. What the flames left was nothing more than an area of earth completely covered in ash and soot.

Adam narrowed his eyebrows. "Wouldn't such a technique burn a lot of prana?" He asked.

Caster smiled a little, a girlish smile with a dark tint. That was the first time he'd expressed any emotion since his summoning.

"Perhaps. But not on a human."
