There was no path. Now they were descending the steeper face of the sierra, and the way led over bottomless crevasses, sheer drops and sheer ascents, sheets of traitorous glare ice. Place after place had to be crossed on the air, and both grew weary with the effort such crossings cost. They hoarded their strength, helping one another; one alone might never have won through. It was starry night already when they saw the light from the Watcher's cave. The light shone watery and dim from beneath the hoary back of the glacier, and as they came nearer they saw why: the cave entrance was sealed by a sheet of ice, a frozen waterfall that fell motionless from the rocks above. They heard no sound. The two young people stared for a long minute, intrigued and fearful. Both had heard of this place, and the ancient who lived there to keep watch on the Ryzga mountain, as a part of the oldest legends of their childhood; but neither had been here before. But this was no time for shyness. Var eyed the ice-curtain closely to make sure that it was real, not dream-stuff; then he struck it boldly with his fist. It shattered and fell in a rain of splinters, sparkling in the light that poured from within. * * * * * They felt the Watcher rouse, heard his footsteps, and finally saw him--a shrunken old man, white-haired, with a lined beardless face. The sight of him, more marred by age than anyone they had ever seen before, was disappointing. They had expected something more--an ancient giant, a tower of wisdom and strength. The Watcher was four hundred years old; beside him even Groz, who had always seemed so ancient, was like a boy. The Watcher peered at them in turn. "Welcome," he said in a cracked voice. He did not speak again; the rest of his conversation was in thought only. "Welcome indeed. I am too much alone here." "You were asleep!" said Var. Shock made his thought accusing, though he had not meant to be. The old man grinned toothlessly. "Never fear. Asleep or awake, I watch. Come in! You're letting in the wind." Inside the cave it was warm as summer. Var saw with some surprise that all the walls were sheathed in ice--warm to the touch, bound fast against melting by the Watcher's will. Light blazed in reflections from the ice walls, till there was no shadow in the place. Behind them began a tinkling of falling water, thawed from the glacial ridges above to descend sheet-wise over the cave mouth, freezing as it fell into lengthening icicles. The old man gazed at his work for a moment, then turned questioningly to the young pair. "We need a little rest out of the cold," said Var. "And food, if you can spare it. We're pursued." "Yes, yes. You shall have what I can give you. Make yourselves comfortable, and in one minute.... Pursued, eh? A pity. I see the world is as bad as it was when I was last in it."
