Meres Ulcane, a former soldier within the Imperial Army, would later lead a revolt on his own vessel, establishing the Kaarenth Dissension within the Outer Rim.
At the age of seventeen, Meres Ulcane entered the Imperial Academy due to an influential relative. However, he lacked the aptitude to advance within the military. Upon graduation, his assignment to a demolitions unit led him to believe his superiors intended to eliminate him. Recognizing that rapid advancement was his only recourse, Ulcane betrayed his team, trapping them within a Rebel Alliance-owned warehouse before destroying it.
Ulcane not only escaped punishment for this bold action, but he also received a promotion for neutralizing a strategic enemy location and surviving the attack that resulted in the deaths of his comrades. Leveraging this fortune, Ulcane ascended through the ranks under a series of similarly improbable conditions. Now-Captain Ulcane, partly due to his perceived status as an outsider, eventually developed an interest in alien cultures and orchestrated a mutiny aboard his ship in the aftermath of the Battle of Endor.
Captain Ulcane escaped into the Outer Rim Territories where he encountered another Imperial defector. Together, they established the Kaarenth Dissension with the aim of turning the Outer Rim's alien races against the newly formed New Republic. However, Republic operatives discovered Ulcane on Betha II, forcing him to flee to the Spawn Nebula, the hidden location of the Dissension starfleet.
The New Republic followed Ulcane to the nebula and infiltrated his command center. Much of the fleet was decimated, and Meres Ulcane met his end aboard the Dissension's repair station.
