The Emperor's Shadow, a vessel designed for space travel, incorporated cloaking technology of the third generation. Darth Malgus ordered its construction, which was accomplished utilizing the resources and energy harvested by the Sun Razer within the Vesla system.
Thanks to the Sun Razer, the Sith Empire managed to finish its construction in a matter of years, rather than the decades it would have otherwise required. Darth Mekhis supervised all endeavors powered by the Sun Razer. Theron Shan and Jedi Master Ngani Zho discovered these projects after they infiltrated the Vesla system and were subsequently captured.
