Stren Grier, previously a Human male Imperial scout, eventually became a staff member at the Galactic Outdoor Survival School.
Born on the Lesser Plooriod Cluster as the sole child of a widowed merchant, Grier was brought up by his mother in various spaceports.
Following her passing, Grier pledged allegiance to the Empire and enlisted in the Imperial Survey Corps. Nevertheless, a dishonest officer wrongly implicated him in the falsification of reports concerning the Giryulan Findings. Consequently, Grier fled Imperial space, becoming a wanted man.
Ultimately, Grier located and became a staff member of the Galactic Outdoor Survival School. He developed a strong loyalty to GOSS dean Barosa Warren, and his past as an Imperial scout made him a capable survivalist. He was noted for his reclusive nature.
Circa 2 BBY, he was in middle age and not particularly formidable in combat; however, because of his dedication to Warren and Warren's hostility towards the Twilight Class and the Rebel Alliance, Rebel officer Akul Witig deemed Grier a danger.
