question:  What power does Var possess?
context: But its outward perils could not compare with the Ryzgas themselves, who slept within, ready to wake and conquer.... The ice-wind blew from the glacier, but Var's love was round her as a warming cloak, a cloak that glowed softly golden in the deepening twilight, even as her love was about him. Var said, "The Watcher's cave should be three miles beyond this pass." Var sensed her fear, and the love that had conquered it. For the flame that had sprung between them at the Truce of New Grass, she had challenged the feud of their peoples and had left her home, to follow him. Now, if her father and his kinsmen overtook them, it would be death for Var, and for Neena living shame. 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. 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. Warming to the old man now, Var sketched his and Neena's history briefly. Var nodded somberly, thinking that an old recluse would in any case be able to do little for them against Groz and his violent kinsfolk. The Watcher was broodingly silent; his eyes shifted to Neena, where she nestled by Var's side. Now for the first time Var sensed the power in the old man's look, the power of four hundred years' wisdom. "Because of them we must build with dreams instead of iron, and our only fire is that of the Sun, and even now, two thousand years later, the Earth is still slowly recovering from the pangs and poison of that age.
