young. From outside, nothing of the building's interior could be made out, for a screen of dense shadow blocked the oval opening. Kial hung back, shivering, as Alston strode to the doorway. "Wait here if you like," he said. "At least till I look around inside. There have been changes since I was last here. All this growth is new...."Panic shrilled through her as she glanced about at the grotesque shadow-shapes. "I'll go with you," she said quickly. "I'm afraid to stay out here alone."

Ranged about the terraces, they parodied the attitudes of worshippers within some unholy temple. Each massive wall was thickly tapestried in matted hangings of the ophidian vines,
