What One Sees and Hears

"Come in, Merlin."

Wizard Leo's voice wafted out from the house, sounding somewhat raspy.

Merlin pushed the door open immediately and walked in. He lifted his head to look, only to discover that Wizard Leo, who used to be full of vigor and energetic, now had an extremely weary expression on his face. Even the blood-colored light emanating from Darkness Eye on his forehead was somewhat dim.

"Teacher Leo, what had happened to you?"

Merlin could not help but ask immediately.
