Velcar Imperial remnant

Following the Battle of Endor and the destruction of the second Death Star, various Imperial splinter factions arose in the wake of Emperor Sheev Palpatine's death. One such remnant faction established itself in the Velcar sector, declaring itself independent from the fractured Galactic Empire.

History
In 4 ABY, the powerful Galactic Empire suffered a devastating defeat over Endor at the hands of Rebel Alliance, ultimately resulting in the destruction of the second Death Star and deaths of both Emperor Sheev Palpatine and his enforcer Darth Vader. This resulted in the Imperial fleet becoming scattered, and, as a consequence of the emperor's untimely demise, the creation of a massive power vacuum. As the Empire struggled to anoint a new leader, various splinter groups and remnant factions began to separate themselves from the central authority on Coruscant, led by warlords seeking to consolidate power in their own regions. It was during this time when Governor Ecressys, an Imperial sector chief from the Velcar sector, sought to cement his own ultimate authority, causing him to establish his own ascendancy in his region.

A region that was already relatively self-sufficient, the Velcar sector proved to be successful under Ecressys' management, standing separate from the imploding Imperial government. In order to better ensure that he could control his people, Ecressys locked down his domain in order to ensure that news of the war did not reach the ears of the ears of the populace. Just as Governor Adelhard of the Anoat Sector did, Ecressys lied to his subjects by informing them that news of the emperor's death was nothing more than Rebel propaganda.

As the war continued to drag on, the Velcar remnant did its best to distance itself from the wider conflict. Ecressys did not partake in Operation: Cinder and he was one of the Imperial warlords not to send troops to bolster Gallius Rax's armada as it assembled at Jakku and prepared to engage the recently established New Republic. This would ultimately spare the Velcar remnant from suffering defeat at the hands of the New Republic.

Once the Galactic Empire surrendered to the New Republic the two factions signed the Galactic Concordance, which stated that remaining Imperial forces were to relocate to a reorganized Imperial sovereignty in the Core Worlds and Inner Rim. While some warlords were permitted to remain independent, Ecressys was worried that he would be branded as a war criminal along with many other imperials who refused to accept the conditional surrender. In turn, the governor abandoned his territory and fled remnant space, escaping to the Western Reaches along with the wealth of countless worlds that he oversaw.

By the time that the New Republic arrived in the Velcar sector to announce its victory, the Imperials had no governor to lead them. Disorganized, the remnant would have no choice but to sign the treaty.
