He had to find a way out, which did not seem all that likely now, as he'd made the (in retrospect) mistake of going down to a lower level. But he chose the direction from which there came the strongest flow of air, and began to move as quickly as he could. The faster he ran into the wind, the more brightly his kienspan burnt. But it burnt less brightly as time went on. He tried lighting a fresh one, but it, too, burnt feebly unless he waved it in the air, and then the light flared up and shone between the heavy bars of the wooden cage that kept the rocks from crushing him on all sides, and cast rapidly moving shadows, sometimes looking like angry faces of mangled giants, or huge ostrich-skeleton-monsters with scimitar teeth: all of which went together neatly with the deafening chorus of moans and wails made by all of the passageways as the breath was sucked out of them.
