In 0 BBY he was on board of the Kuari Princess to observe and eventually arrest Detien Kaileel, who was supplying weapons to the Rebellion. While there he met an old friend and lover, Celia Durasha, whom he hadn't seen in seven years. When she tried to escape the Princess with Kaileel, Adion stopped them, killing Kaileel but was unable to stop Celia from escaping and was cut several times with a vibroknife given to her by her dead twin.
