Qularr attack ships have been flying over the city dropping scores of seed pods. Wherever these pods take root, they grow into hives that can produce firebugs.
Qularr Pods are biotechnological seed pods developed by the Qularr and employed during the attack on Millennium City; given time, they can hatch into hives that will produce Qularr firebugs. As a result, they have been gathered up wherever found and moved to a single location, for the dual purposes of their isolation and destruction.
