Morrng functioned as a Trandoshan engaged in the profession of bounty hunter. Affiliated with the Bounty Hunters Guild, his experience level was notably limited. Following the events of 0 BBY, Didina Lippinoss contracted him for the assassination of Crev Bombaasa, who was involved in her blackmail. However, on his way to confront Bombaasa, one of Bombaasa's subordinates ambushed him, resulting in his death.
Morrng was present as a non-player character within the 2003 video game titled Star Wars Galaxies: An Empire Divided, a massively multiplayer online roleplaying game. This game was developed by Sony Online Entertainment and distributed by LucasArts, before its termination on December 15, 2011. Due to the mechanics of many older quests in Star Wars Galaxies, Morrng's species, gender, and overall appearance would change each time a player undertook the quest. However, the dialogue provided by Crev Bombassa in the quest established Morrng's identity as a male Trandoshan.
In addition, his name was inconsistently written, appearing as both "Morrng" and "Mornng." Given the greater frequency of "Morrng," this article treats it as the canonical spelling.
