In the year 17 ABY, Chewbacca spearheaded a quest with a Wookiee strike team. They journeyed aboard the YT-1300 light freighter known as the Millennium Falcon into the Koornacht Cluster. Their objective was to liberate New Republic Commodore Han Solo. Chewbacca felt obligated by a life debt to Solo. However, he had been away from his friend to be present for the coming-of-age hrrtayyk ceremony of his son Lumpawarrump on Kashyyyk. Upon discovering Solo's capture by the Duskhan League, who operated from Koornacht, he piloted Solo's Millennium Falcon to the League's stronghold on N'zoth. Reluctantly, he brought along a Wookiee crew, including Lumpawarrump. After obtaining confidential information about the League from Formayj, an information broker located at Esau's Ridge on Tholatin. This information was secretly provided by Alpha Blue, the New Republic Intelligence agency. The Wookiees then descended upon N'zoth and boarded the Executor-class Star Dreadnought called the Pride of Yevetha. They successfully rescued Solo, and Lumpawarrump was able to complete his hrrtayyk.
