They care nothing of power, honor, nor glory. They care only to serve.
—Rellius Umber, speaking about the Umber Guard.
The Umber Guard, known formally as the Protectors of Galactic Order and coloquially referred to as the Enforcers, was an order of Force-sensitive elites that served the Central Galactic Authority as the personal security force of the organization's leadership and unquestionably-loyal agents of its will.
Formed primarily from the Knights of the Empire's remnants by Rellius Umber and touted publicly as a reformed version of the order, the Umber Guard was actually a Sith-aligned organization composed of imprisoned Imperial Knights who were corrupted by the power of Darth Sunder, the Dark Lord of the Sith.
