The War-Faith constituted the regional armed forces stationed on Shu-Torun, a planet dedicated to mining within the Mid Rim. These forces, under the command of a celebrant warlord, were responsible for eliminating threats to the planet. During the Galactic Empire's reign, Hollian, the oldest daughter of the King of Shu-Torun, was in line to inherit the role of celebrant warlord following her father's death. Nevertheless, both she and her father perished when their assassination attempt on the Sith Lord Darth Vader failed during a visit.
The initial reference to the War-Faith occurred in Darth Vader Annual 1, a comic book penned by Kieron Gillen and published in 2015.
