The only visible reaction from Artemis was the way that his pupils dilated on their background of gold and bright green. The ability to keep his expression blank was one of the first things that Artemis learnt when he was first brought to the Unseelie Court. And if he had not mastered it, he probably would not still be alive.

The battle had caused adrenaline to thrum through his veins. Violence didn't bother him; it was nature to his kind. But seeing Koltira in such a state was something else entirely. It was the sight of that sword in particular that was enough to deeply unsettle him. The overall scene was enough to remind him of things he had only seen in the depths of the Sithen. It made him feel much younger and more powerless than his over a century and a half of age, as only the older fey he had encountered thusfar in his life had managed before.

It was all enough to draw a flight response from just about anyone with common sense, but he found himself standing his ground almost stubbornly. The logic was all quite clear in his mind: you didn't flee from a predator unless you wanted to make yourself look like prey. He fought to tear his eyes away from Koltira and instead turned his attention to the soldiers that had yet to be affected by the spreading plague, aiming one of his arrows and letting it loose.
