Rimsen was a male officer in the New Republic Defense Fleet. In 25 ABY he held the rank of captain and commanded the Corusca Fire. A native of Agamar, he took his ship off his assigned course back home when he became suspicious after his planned course was altered to take him away from Vector Prime. Arriving at Agamar, he learned from his family of Leia Organa Solo's visit there to recruit support for the war against the Yuuzhan Vong. Rimsen ordered the Corusca Fire to rendezvous with the Ralroost and participated in Traest Kre'fey's relief of the Battle of Dantooine.
