"N-no!" shouted Arcem as he looked at Arya with a terrified expression. "Shhh, you're okay. This will only hurt a lot," replied Arya, pulling out the dagger ready to strike.
"Light bless us with your might. Fix -" Arcem tried chanting before his neck was torn off. Arya quickly turned around and jumped back a few spaces barely avoiding the strike of a black figure as he turned the dagger in his hand from a stabbing position to a slicing position, with such proficiency that one would think he had been using a knife all his life.
"How come I didn't hear it?" thought Arya as he realized the reason Arcem was looking at him with such a terrified expression, even though he had not yet seen the dagger. He wasn't looking at him but at the beast behind him.
