When the planet's rich mineral deposits, including coralline and ostrine, were discovered by the Galactic Empire, which subjugated the world, installing a garrison and advanced refineries. The Empire made the local ruler, Makintay, Imperial Governor. The planet's six cities included the capital, Arginall City.
The first Rebel uprising in Arginall City was led by Merak and Stevan Makintay, the disinherited eldest son of the Governor.
Local Ketrian Altronel found a way to modify ostrine into a heat-absorbent. Ketrian defected to the Rebel Alliance and added her ostrine-derived absorbent to the housings of X-wing cannons, improving their firepower.
