 What power does Var possess?
Var sensed her fear, and the love that had conquered it. 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. Now for the first time Var sensed the power in the old man's look, the power of four hundred years' wisdom. He was momentarily uncertain that he and she were real and here, such had been the force of the dream, a vision of such scope and reality as Var had never seen—no, lived through—before.
