Slowly, he turns back to Vernasus. "You fool..." He shook his head slowly. "That was Arsenic Trioxide." He brought his hands up quickly, breaking Vernasus' hold on him and pushing the other brother back a step. "We have to clean this up immediately, it's incredibly toxic. A sprinkling here there, not so bad." He said, gesturing at Vernasus' rash. "That entire bag, mixing in the air..." He looked Vernasus directly in the eye. "If you don't follow my directions exactly, people will die, the entire library will bee contaminated."
