Produce a detailed written description of a foreboding scene outside the wilderness with a ravine, a bridge, and a keep.

A wide canyon opens up ahead, the jagged path dropping off into nothingness. Along the edge of the cliff grow scraggly vines and plants, in deep green and pale violet colors, clinging to the drab brown rocks of the mountain. Far from the bottom of the ravine rise the sounds of the quarry -- stone grinding and the hollow echo of metal picks and chisels hammering against rock. A narrow steel bridge stretches across the ravine, and a large granite keep can be seen on the other side.
