They stood now, all three of them, wet through, behind the curtain until the shadow of the demon faded and vanished. Finally Honath felt a hand thumping his shoulder, and turned slowly.
Speech was impossible here, but Alaskon's pointing finger was eloquent enough. Along the back wall of the falls, where centuries of erosion had failed to wear away completely the original soft limestone, there was a sort of serrated chimney, open toward the gorge, which looked as though it could be climbed. At the top of the falls, the water shot out from between the basalt pillars in a smooth, almost solid-looking tube, arching at least six feet before beginning to break into the fan of spray and rainbows which poured down into the gorge. Once the chimney had been climbed, it should be possible to climb out from under the falls without passing through the water again.
And after that—?
Abruptly, Honath grinned. He felt weak all through with reaction, and the face of the demon would probably be grinning in his dreams for a long time to come. But at the same time he could not repress a surge of irrational confidence. He gestured upward jauntily, shook himself, and loped forward into the throat of the chimney.
Hardly more than an hour later they were all standing on a ledge overlooking the gorge, with the waterfall creaming over the brink next to them, only a few yards away. From here, it was evident that the gorge itself was only the bottom of a far greater cleft, a split in the pink-and-grey cliffs as sharp as though it had been riven in the rock by a bolt of sheet lightning. Beyond the basalt pillars from which the fall issued, however, the stream foamed over a long ladder of rock shelves which seemed to lead straight up into the sky.
"That way?" Mathild said.
"Yes, and as fast as possible," Alaskon said, shading his eyes. "It must be late. I don't think the light will last much longer."
"We'll have to go single file," Honath added. "And we'd better keep hold of each other's hands. One slip on those wet steps and—it's a long way down again."
Mathild shuddered and took Honath's hand convulsively. To his astonishment, the next instant she was tugging him toward the basalt pillars.
The irregular patch of deepening violet sky grew slowly as they climbed. They paused often, clinging to the jagged escarpments until their breath came back, and snatching icy water in cupped palms from the stream that fell down the ladder beside them. There was no way to tell how far up into the dusk the way had taken them, but Honath suspected that they were already somewhat above the level of their own vine-web world. The air smelled colder and sharper than it ever had above the jungle.
