 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.... While she waited he spun a dream, attaching it to the crags that loomed over the pass, and to the frozen ground underfoot. 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. The Watcher regarded them with compassion as their eyes brightened and some of the shadow of weariness lifted from them. 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."
