Unlike other worldships at the time of the Yuuzhan Vong War, the Domain Hul had one distinct difference—it was healthy, and could participate in battle. As such, Warmaster Tsavong Lah selected it to serve as the flagship of Supreme Commander Czulkang Lah, his father, during the Battle of Borleias. During the campaign, General Wedge Antilles and Commander Eldo Davip developed Operation Emperor's Spear, where they would have the Lusankya ram the worldship, in an attempt to both destroy a healthy worldship and kill Czulkang Lah. The operation was a success, and the Domain Hul was destroyed.
