Iceglaze Base, located on Hoth, was the secondary base of operations for the pirate Salmakk during the Galactic Civil War. Its main purpose was the harvesting of lumni-spice due to its close proximity to a dragon-slug warren. The lone safe path to the outpost was supposedly known only by Salmakk and his crew.
