"I saw it," said Dhuva faintly. "But it moved so fast ..."

"You're safe here for the moment," Brett said. "There are none of them around. But they may be back. We've got to find a way out!"

Dhuva started up, staring around. "Where am I?" he said hoarsely. Brett seized his arm, steadied him on his feet.

"We're in a hollowed-out cave," he said. "The whole city is undermined with them. They're connected by tunnels. We have to find one leading back to the surface."

Dhuva gazed around at the acres of bones. "It left me here for dead."

"Or to die," said Brett.

"Look at them," Dhuva breathed. "Hundreds ... thousands ..."

"The whole population, it looks like. The Gels must have whisked them down here one by one."

"But why?"

"For interfering with the scenes. But that doesn't matter now. What matters is getting out. Come on. I see tunnels on the other side."
