Zayne Carrick joins forces with the same Masters who murdered his fellow Padawan in a desperate attempt to save the galaxy from the Mandalorians! Arkanian Lord Adasca holds the Republic and the Mandalorians hostage, offering a weapon of unrivaled power to the highest bidder, but not even Zayne and his former Master Lucien Draay can stop Adasca from unleashing unthinkable devastation in pursuit of profit. Then, back on Taris, Zayne finds himself allied with Master Raana Tey in a mission against the marauding Mandalorians - but Tey may be more interested in destroying Zayne than she is in saving the planet!
