Cassius took interest in Jenso's interaction, he even chuckled at the man as he took note of his Pyromancer capabilities... But he sensed he was far stronger than he let on; Cassius strength paled in comparison. But he could tell there was much more to his demeanor than he let on. But he did not quite have time to talk, but the matter seemed far more serious once he heard the King's Knight speak.

He formally removed his helmet; his long silky smooth hair blowing in the wind, as he looked to Polaris. "I am Cassius Alexandros Lumya Svent. A Lumyian from Lumyia as you can clearly deduce. But a mary band out here in the open seems quite dangerous if people wanted to snuff out any hope of saving your monarch, wouldn't you agree Sir Knight?" Cassius' eyes were well trained. His hazel eyes staring into Polaris'. "I can see by the temperament of your eyes that you're well trained in hand to hand combat. Your eyes do not let go of a single detail." Cassius dropped his act really quickly. Granted magic could be used for entertaining purposes. But he was in the presence of a man under the monarch. 

"It is clear to me this letter was a waste of my time if this was what it was meant for... They only disguised it if they knew I would not want to be in battle..." He lamented for a moment. "Yet, doing nothing feels like the wrong thing to do... Very well... If you'd like me to be here as a man who channels from the abyss, than I suppose I can be the hand you need me to be... But the moment you do any sort of wrong doing... I will leave where you stand. Promise me as a King's Knight, that you strive to do the right thing. Hold your oath, and in turn you hold mine as a committed person of causality."  Cassius extended his right hand to the King's men.
