Dedlanite was a mineral used in the manufacture of blasters, and could power them. It could be found in the Andelm beetle caverns on the planet Andelm IV. During the Galactic Civil War, the crime lord Jaum forced miners to collect dedlanite, which he sold to the Galactic Empire. Years later, the First Order mined for dedlanite in asteroids at Station Theta Black.
