Darth Ominus (Cail's Empire)

"In his presence, all hope evaporates. In his presence, you know true despair. What makes him formidable is his power; what makes him terrifying is his resolve."

- A Jedi Master that survived a duel with Darth Ominus, 13 ABY

Darth Ominus, also known as the Infinite Emperor or, occasionally by his supporters, as the True Emperor, was a Human male from Bakura that was also a Dark Lord of the Sith during the Galactic Civil War and the leader of the Infinite Empire of the Sith. After he revealed his existence to the galaxy, he took on a new title, naming himself the Lord of Despair.

The man that became Darth Ominus was born on the planet of Bakura in the Outer Rim in the final decades of the Galactic Republic. At some point shortly before the Stark Hyperspace War, Ominus left the known galaxy, either willingly or against his will, as a child, and ventured deep into the Unknown Regions. There, discovering he was Force-sensitive, he began learning the ways of the Sith and harnessing the dark side of the Force. He grew close with his Sith Master, who was also the leader of the so-called Infinite Empire of the Sith, which controlled vast territories in the Unknown Regions. Some time around the Battle of Yavin, he killed his master in a duel and took on the mantle of Dark Lord of the Sith, assuming control of the Empire.

In 10 ABY, shortly after the end of the Imperial Civil War, he invaded the known galaxy in an attempt to destroy both Cail's Empire and the Galactic Federation, which were both deemed as being too weak and unable to resist an invasion by his spies. His entry into the Galactic Civil War threw the galaxy on its head and complicated the galactic conflict even more. His apprentice, Darth Xyster, aided him in his war against the Imperials and the Galactic Federation.

Behind the scenes
Darth Ominus' name has two points of origin. Ominus is a alteration of the word dominus, Latin for "master" or "lord". It is also drawn from the English word ominous, which means "being or exhibiting an omen; foreboding or foreshadowing evil".
