The Griren Province existed on the Inner Rim world of Hapor. During the year 0 ABY, the Hand of Judgment, a squad comprised of five stormtrooper defectors from the Galactic Empire, took part in a minor water-related disagreement within the province. Mara Jade, an Emperor's Hand, reviewed an account of the Hand of Judgment's participation in this incident within a period of three months following the disagreement.
Timothy Zahn referenced the Griren Province in his novel Choices of One, published in 2011.[1]
