The pain within his heads was monstrous. A fearful wrenching that became the sucking of a million mouths. His very brains were pulled upon, pressured, compressed, and then purged.

Semph and Linah looked away from the pulsing body of the dragon to the drainage tank across the chamber. It was filling from the bottom as they watched. Filling with a nearly colorless roiling cloud of smokiness, shot through with sparks. “Here it comes,” Semph said, needlessly.

Linah dragged his eyes away from the tank. The dragon with seven dog heads was rippling. As though seen through shallow water, the maniac was beginning to alter. As the tank filled, the maniac found it more and more difficult to maintain his shape. The denser grew the cloud of sparkling matter in the tank, the less constant was the shape of the creature on the beaming stage.

Finally, it was impossible, and the maniac gave in. The tank filled more rapidly, and the shape quavered and altered and shrank and then there was a superimposition of the form of a man, over that of the seven-headed dragon. Then the tank reached three-quarters filled and the dragon became an underling shadow, a hint, a suggestion of what had been there when the drainage began. Now the man-form was becoming more dominant by the second.

Finally, the tank was filled, and a normal man lay on the beaming stage, breathing heavily, eyes closed, muscles jumping involuntarily.

“He’s drained,” Semph said.

“Is it all in the tank?” Linah asked softly.

“No, none of it.”

“Then…”

“This is the residue. Harmless. Reagents purged from a group of sensitives will neutralize it. The dangerous essences, the degenerate force-lines that make up the field… they’re gone. Drained off already.”

Linah looked disturbed, for the first time. “Where did it go?”
