Diran Miciluz was a weapons designer working for Hydrospeare Corporation. Miciluz was a native of the Ktilac Regions, a part of the galaxy with few Human inhabitants. This led many to believe that his parents were probably traders or scouts. Miciluz's green hair also suggests that he descended from the crew of RSF Invincible-class Dreadnaught Noble, lost centuries ago. The Rebel Task Force discovered that Miciluz had helped improving the range and accuracy of BlasTech HY-6 heavy cannons, which were being increasingly used by the Empire in aquatic applications.
