The Brood was dispatched to secure the Xel'Naga artifact on Bhekar Ro. The zerg successfully made planetfall and began infesting the area around the artifact and the local terran colony of Free Haven. An assault on the colony was thwarted by the intervention of Alpha Squadron. By that time the Brood's attention was focused on removing the protoss presence from the artifact. Ultimately the Brood was unable to secure the artifact. Following a terran nuclear strike the energy creature that emerged absorbed all of the protoss and zerg on and near the planet. The Brood was effectively destroyed.
In the process of infesting the planet, the Brood absorbed a dog named Old Blue. From Old Blue was bred the "Roverlisk". However, this strain was destroyed along the entire Brood.
