Write a detailed description of a foreboding scene outside a canyon with shrubberies and walls.
assistant
A pair of green-tinged shrubberies stand beside a dark opening in the sheer cliff face in the face of a sheer cliff, almost like squat, silent guards. High stone walls rise up on either side of the pass, limiting the view to a rectangular patch of star-dotted sky, its bespeckled surface masked by thin, tattered clouds. The narrow cleft through the mountain continues northward.
