Yug'Voril is located inside a large cavern on an island surrounded by a lake. The walls of the cavern are lined with veins of blue crystal, and stretch far up into the darkness well beyond the range of sight. The shore is comprised of a type of gravel very similar to sand. The water surrounding the island is fresh water and clear enough for one to see into the lake provided that the person has light. The cavern is very humid, and the temperature is cold.
