The magic was seething, he could feel it, but there was something there, something like -- the opposite of growing, but still related somehow. Spencer drew in a breath and closed his eyes, William's hand keeping him anchored.
"Effloresco," he murmured, and the rune began to glow. Spencer drew in a breath, then gritted his teeth as the magic coming from the bindrune seemed to ratchet up another level, setting him on edge. It was working, though, and he thought again, the opposite of growing, and then, with grim pleasure, not for long.
