Mirrian was a female who existed during the time of the Galactic Civil War. Following the Battle of Yavin, Mirrian took up residence in the former home of her parents. She was the sibling of Wolff Kalos, a Rebel Alliance officer.
The character Mirrian was referenced in the 2003 video game Star Wars Galaxies. This game was a massively multiplayer online roleplaying game that was created by Sony Online Entertainment and distributed by LucasArts, before its servers were shut down on December 15, 2011. Mirrian's name came up in the fourth part of the "Secrets of the Syren" questline, which was added to the game with "Publish 21," on August 4, 2005. The "Secrets of the Syren" storyline was later removed from the game when "Chapter 1," went live on June 8, 2006, due to big changes planned for Rori with the introduction of the Battle of Restuss.
Within the fourth quest of the "Secrets of the Syren" story arc, the player had the option of siding with either Wolff Kalos or Imperial Officer M'Kae. This document assumes the player sided with the Rebel Alliance. If the player instead sided with the Empire, they would have to threaten Mirrian to get information from Wolff Kalos.
