A single millimeter of mistake would have been fatal. Arthur was always moving at the right place, at the right time. It was as if he could perfectly predict the chaotic battle occurring before him.
Slowly, Arthur had managed to sneak in the chaos. The theory of his entry was sound and irrefutable, but the application was frightening. Electrocution, explosions, shockwaves, desolation or the lust of the Empress could all kill Arthur. But this lion's den proved useless against Arthur's eyes.
As the Overcomers noticed Arthur, they made sure that the Empress wouldn't notice it.
The chaos of the battle that was happening before him immediately intensified. Yet even then, Arthur was able to maintain his cloak. Any other person would have failed. But not Arthur. He knew where he must be and where to go.
