Rejoice! For I have come to liberate you from your existence and return you to the abyss.
—Umber Noth during the Conquest of Coruscant.
Umber Noth, regarded as the "Herald of Nightmares", was a powerful Sith Lord who served as the supreme commander of the Noth dynasty's Sith Empire. As the last-living son spawned from the union between Emperor Onderyx Noth and Zenigul Noth, he was also crown prince of the empire and heir to the Imperial throne. During the reign of Onderyx, Umber loyally fought to enforce his family's rule and conquer new territories in the name of his father.
