Amara Jedselk, a female Human, held the rank of Commander within the Imperial Army during the Rebellion era. She was stationed at the garrison located on Sellasas. Moreover, she was the daughter of Governor Jedselk, who at that time, governed the planet.
Following the Battle of Yavin, a Rebel team initiated a siege targeting the planet Sellasas, aiming to eradicate the Imperial presence. Jedselk, serving as the second-in-command of the army garrison, engaged in combat against the Rebels during their ultimate attack on the base. Despite sustaining multiple injuries during the conflict, Jedselk survived, even rescuing a critically wounded Srrors'tok male civilian who had joined the fight against the Rebel invaders. Together, they evaded capture and remained alive for several days. The Rebel strike team withdrew from the planet within a week after completing their final assault on the garrison. Three days later, a navy relief force, led by Admiral Kedler, arrived and recovered the two.
During their period of healing, Jedselk bestowed the adoptive name Tyionsis Cex upon the Srrors'tok, strengthening their connection. Cex pledged a life debt to Jedselk for saving his life and developed a deep, personal fondness for her throughout their recovery. Eventually, Jedselk received a new assignment, and Cex was presented with the opportunity to repay his life debt by serving her father as an Imperial bounty hunter, an offer he accepted.
