Siron Vurn'ke existed as a male Weequay criminal figure on the desert planet of Tatooine during the Galactic Civil War era. Following the Battle of Yavin, he held the position of captain over a band of Weequay enforcers, all under the employ of the Hutt crime lord known as Jabba Desilijic Tiure. In the year 1 ABY, Jabba assigned Vurn'ke's group of assassins the task of eliminating a skilled pilot who was loyal to Lady Valarian, the head of the Valarian Syndicate and Jabba's primary competitor. However, Lady Valarian became aware of the plot and gave her henchman a warning. Subsequently, the spacer located and engaged Vurn'ke and four Weequay fanatics in combat near Mos Eisley. Siron Vurn'ke met his end during this violent confrontation.
Siron Vurn'ke was featured as a non-player character within the 2003 video game Star Wars Galaxies. This game was a massively multiplayer online roleplaying game, developed by Sony Online Entertainment and brought to the public by LucasArts, before its servers were shut down on December 15, 2011. Siron Vurn'ke was included in the game's initial release, specifically as part of Lady Valarian's Quest Series.
With the implementation of "Publish 23" on August 31, 2005, Lady Valarian's Quest Series was removed from the game, which resulted in Siron Vurn'ke's removal as well.
