Design Team Beta was a team of four hand-picked specialists who worked for Hydrospeare Corporation during the times of the Galactic Empire. Led by Tolum Harous, the other members included Diran Miciluz, Mosara Thiirn and Sere Lure. Before 1 ABY, the team was led by Dr. Plo Smarx, but Smarx was arrested by the Empire and replaced by Harous. Due to the quality of Design Team Beta's products, the Empire provided Hydrospeare with two dozen of new projects around 2 ABY, leading some Rebel officers to believe that the Empire was trying to recover Mon Calamari.
