In the year 382 BBY, a mission was launched by Jedi Master Silandra Sho's Pathfinder team to the planet Gloam. Their objective was the recovery of Outer Rim Expedition Two-Five-Two.
The junior novel The High Republic: Quest for the Hidden City, which was penned by George Mann in 2022, marked the initial appearance of the Gloam mission. This novel was part of Phase II of the Star Wars: The High Republic multimedia project.
