 How does The Watcher communicate with others?
But its outward perils could not compare with the Ryzgas themselves, who slept within, ready to wake and conquer.... Which of the two was worse was no longer a simple problem to Var, who had grown much older in the last days. While she waited he spun a dream, attaching it to the crags that loomed over the pass, and to the frozen ground underfoot. It was black night, as it would really be when Groz and his henchmen reached this place; lurid fire spewed from the Ryzga mountain, and strange lights dipped above it; and for good measure there was an avalanche in the dream, and hideous beasts rushed snapping and ravening from the crevices of the rock. It was starry night already when they saw the light from the Watcher's cave. 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. The Watcher was four hundred years old; beside him even Groz, who had always seemed so ancient, was like a boy. 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. 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. Hot food and drink were before them almost at once. The Watcher regarded them with compassion as their eyes brightened and some of the shadow of weariness lifted from them. Warming to the old man now, Var sketched his and Neena's history briefly. And before very long, I'm sure, I would have performed some deed which Groz would recognize as a worthy exploit, and would thus have healed the feud between our families. I would like to help you—but, you understand, I am the Mountain Watcher. I must be above feuds and families." "We haven't much choice, since they're overtaking us. The Watcher was broodingly silent; his eyes shifted to Neena, where she nestled by Var's side. That is the second part of the law the First Watcher made: to guard lest the unwary and the ignorant should bring harm on themselves and on all men." "In the hollow heart of their mountain the Ryzgas sleep, as they chose to do when their world crumbled. But if they are wakened, the mountain will tremble, and the Ryzgas will come forth."
