Demolitions Squad 419 functioned as a military arm of the Galactic Republic throughout the duration of the Great Galactic War. Near the conclusion of the conflict, specifically around the signing of the Treaty of Coruscant, the entire squad found themselves imprisoned by the forces of the Sith Empire at the Troida Military Workshop located on Balmorra. Due to stipulations within the treaty, a sanctioned rescue operation was deemed impossible; consequently, a youthful Jedi named Fortris Gall resolved to independently infiltrate the workshop in order to liberate the squad.
