Albers's eyes widened.
What had he just seen?
He had seen Arthur splash the Wailing Banshee with two tubes of concentrated sulfuric acid!
Although Arthur had shouted, "Evil spirit, be purified," what he splashed was definitely not holy water-the formula for making holy water had been lost after the Sacred Age ended, leaving only a few finished samples in collectors' hands.
