The creature known as a howler served as Sabine Wren's mode of transportation on the planet Peridea, a world located in a faraway galaxy, during the mission aimed at locating Ezra Bridger. This animal was part of the supplies bestowed upon her by Captain Enoch and a contingent of Night Troopers. Following an assault by bandits on Wren, the howler initially fled, but later returned, tailing her with an air of contrition. Despite her initial annoyance at its temporary lapse in courage, Wren gradually developed an affection for the creature. During an occasion where Wren and Ezra Bridger aided a band of indigenous Noti in moving their dwellings, the howler secretly boarded one of the pods, remaining hidden as Grand Admiral Thrawn's troops launched an assault on the traveling group.
