BT-413 was a member of the Galactic Empire's stormtrooper forces during the era of the Galactic Civil War. After the Battle of Yavin, this particular stormtrooper served as a security detail at the Imperial Research and Prison Facility located on the planet of Dathomir. Within this facility, Imperial scientists were secretly working on the dangerous re-engineering of the infamous Blackwing virus to create a bioweapon. BT-413's assignment was Security Post 12, which was on Level 1 of the research laboratory. In the year 1 ABY, BT-413 was present when an accident caused the escape of the virus from its containment within the Imperial Research and Prison Facility. This outbreak resulted in the deaths of many individuals in the area, who were then transformed into undead beings.
The character of BT-413 appeared in the video game Star Wars Galaxies, a massively multiplayer online roleplaying game that was initially released in 2003. The game was developed by Sony Online Entertainment and published by LucasArts. The game was shut down on December 15, 2011.
