In Athen Shire there used to exist a small, independent research lab, under the supervision of Dr.Styve. When they recieved a large set of brand new Bio-Zymolots from Eple, they soon started test-production of biomech weapons. The most successfull of these designs were the Cumulus assault rifle models - produced in a limited edition. The lab was soon after ravaged and pillaged by OT paid mercenary forces, and Dr.Styve was perma-killed. Commander Kelly Frederickson and a band of 6 other clan members then hunted the evil-doers down, taking back the stolen weapons. The Commander since kept this rifle.
