Pern was a male human of Waterdeep in the 1350s DR. He was a member of Waterdeep's City Guard. One day in the Year of the Prince, 1357 DR, a huntsman informed the City Guard of a magical tower erected within a single day, a full day's hard ride north of Waterdeep's Trollwall. A City Guard patrol, led by a captain and including Pern, investigated and attempted to scale the tower. Imgig Zu, master of the tower, animated his gargoyle minions to attack the guardsmen.
