Destruction of Gastus IV

The Battle of Gastus IV was the start of the newly-coronated Emperor Valak's great campaign to rebuild the Empire. It was at Gastus IV that Valak introduced the third Death Star to the galaxy.

After swiftly crushing the New Republic defense force in the system, the Death Star was used on the planet, wiping the entire planet and its populace, in addition to the Republic ground forces, off the galaxy.

After Gastus IV, the galaxy was shocked and horrifed to see that the Empire had brought back yet another Death Star.
