The Siege of Sellasas occurred not long after the Battle of Yavin.
In the time of the Galactic Civil War, a Rebel strike team conducted a seven-week siege of Sellasas, culminating in a final attack on the Imperial army garrison. Regrettably, the Rebel commander's focus on eradicating the Imperial presence on Sellasas led to a disregard for civilian safety, resulting in numerous civilian deaths. Tyionsis Cex's family serves as a poignant illustration of the civilian suffering on Sellasas. This Srrors'tok merchant family, indifferent to the politics of the war, tragically perished one after another during the siege. Cex, as the last surviving male of his lineage, chose to fight against the Rebel invaders. Commander Amara Jedselk, the garrison's second-in-command, risked her own life, sustaining multiple wounds, to save the severely injured Srrors'tok during the Rebels' final assault on the garrison. Together, they successfully avoided capture for several days until the Rebel strike team retreated from the planet. A relief force from the navy, led by Admiral [Kedler], arrived three days afterward.
