 What is the Watcher's purpose in spinning the vision of when the Ryzgas fell?
But its outward perils could not compare with the Ryzgas themselves, who slept within, ready to wake and conquer.... While she waited he spun a dream, attaching it to the crags that loomed over the pass, and to the frozen ground underfoot. Var eyed the ice-curtain closely to make sure that it was real, not dream-stuff; then he struck it boldly with his fist. 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.
