By 9 ABY, Tschel held the rank of Lieutenant, and was assigned as a bridge officer aboard the Star Destroyer Chimaera, then serving as the command ship of Grand Admiral Thrawn himself. In the eyes of the flagship's captain, Gilad Pellaeon, Tschel was absurdly young to hold such an important post, with a lack of experience and self-control for which his training and enthusiasm could not compensate—but also all too typical of the young volunteers and conscripts who now made up the bulk of the Starfleet's front-line forces, and hardly to be blamed for his own lack of combat experience.
The subsequent campaign against the New Republic tempered and hardened Tschel and other young officers like him, but little is known of his service over the subsequent decade after the Battle of Bilbringi.
