Human: Produce a detailed written description of a magical scene outside town with a tower, rock formation, and trees. Assistant: 
The softly gleaming silver Great Tower eats up most of the ground of this darkened cobbled courtyard. Twin globes of crystal illuminate the south entrance to the Great Tower, catching on the armor of the tower's guards. A thicket of trees can be glimpsed to the east, and a curious rock formation silhouette catches the eye to the west.
