The moment he heard the crazy laughter, William flashed to the tower guardian's side.
"Close your eyes," he said succinctly.
"What?"
The tower guardian didn't realize what had happened at all. She only looked around at the billowing smoke and asked in horror, "Where is this laughter coming from?"
William didn't waste his breath on her. He used the Shadow spell, Blind, to temporarily blind her.
"If you still want your sanity, don't move until I remove the blinding effect."
The sudden darkness threw the tower guardian into a panic. She was about to say something when the crazy laughter around her stopped.
"What was that…"
Before she could finish asking, an even crazier laughter suddenly erupted. This time, this voice seemed to echo in her ears.
