Sebastian had his blade to Demorales' neck, ready to slice it open. The fear in the man's eyes filled the King with immense satisfaction yet he did not stop because he knew that it was only when the man's blood stained his hands and his blade would his bloodlust be satiated.
From his peripheral, he searched for the princess, finding her where he had left her except now, the witcher whom the witch had insisted was her brother, knelt beside her, helping her tend to the witch.
Sebastian noticed he was chanting something and considering that the princess didn't look tense, he assumed it was not a spell against her.
However, Demorales noticed he wasn't dead yet, despite feeling the coldness of the icy steel blade pressed against the skin of his neck. He opened up his eyes, glancing briefly at the King to see that he was rather distracted.
