Momin

"Empires have risen and fallen since my birth, great ages of the galaxy have passed…but here I stand."

- Momin Momin was an ancient Sith Lord and sculptor. Unlike other Sith, he aspired to make his legacy through his creations. His ideas seized him until a Sith named Shaa went to rescue him. The other Sith, however, considered their history heretical and suppressed. By the time of the Age of the Empire, all his works were believed lost. Darth Sidious, the ruler of the Galactic Empire, possessed a ship that contained numerous Sith artifacts. Korin Pers, an antiquarian expert, told Lando Calrissian that he believed artifacts were created by Lord Momin.

History
At a young age, las ideas and aspirations of Momin got him imprisoned by those who despised his work. A Sith lady named Shaa freed him, claiming Momin as her Sith apprentice and trained him in the dark side of the Force. Momin, though, killed Shaa, feeling he was second to none and began exploring the lore of the dark side. He eventually built a superweapon which had the power to destroy a city, Momin, however wanted to freeze the people in time during their moment of terror. As the Jedi intervened during Momin's attempt, he lost control of the energy he wielded and his physical body was destroyed, leaving only his mask with his consciousness inside.

Many years later, Darth Sidious recovered Momin's mask from the Jedi Archive vault. After learning of Momin's story from the mask, Sidious gave it to Darth Vader as a gift for his journey to Mustafar, which Vader sought to make his personal stronghold. There, the mask killed Vader's Chief Imperial Architect, Colonel Alva Brenne, and possessed her aide, Lieutenant Roggo. As Vader examined the mask, it told him of Momin's past. Vader then allowed it to possess a Mustafarian and grant Momin's consciousness a body. Vader discussed a creation Momin had designed, and agreed to let him build it for him.

Momin, with the help of Imperial resources supplied by Vader, began designing a fortress that could tune the energies of the dark side locus on Mustafar and open the door to the dark side of the Force. While Momin's fortresses were repeatedly destroyed by the incredibly harsh natural conditions on the planet, the ninth design was successful. Shortly after the fortress was finally finished, whilst Vader was distracted by an invasion of Mustafarians, Momin undermined him and opened the door to the dark side. He used it to resurrect his physical body. Vader soon returned to the fortress and used it to obliterate the Mustafarian attackers. Momin then confronted him and, after a short duel, Vader used the Force to ram him with a rock. Momin was crushed against the wall and died.

Years later, Momin's mask was on the Imperial yacht Imperialis. During the ships infiltration, the mask corrupted two infiltrators and the others were forced to abandon and destroy the Imperialis.
