Two Nharwaak CR90 corvettes, Charger 1 and 2, from group Charger took part in the Conflict at Mylok IV during the Galactic Civil War. Nharwaak and Habeen researchers had jointly designed a new experimental starfighter hyperdrive system, yet disagreed on who best to market it to. Habeen researchers arranged for a test bed to be inspected by Imperial Grand Admiral Demetrius Zaarin, to the dissent of the Nharwaak. Corvettes Charger joined a task force of Y-wings to attempt to stop the Habeen arrangement with the Empire.
