The Saliens, a barbaric alien race, have destroyed countless planets- including their own. They invade, divide, and conquer. Every 10 ages they force 10 planets to bring forth their most fiersome warriors to compete for the ultimate treasure- their planets freedom.
50 ages ago the Halmanians were a peaceful race. Crime, war, and murder didn’t exist on their planet until the Salien ship appeared in their planets atmosphere. The planet has survived 4 games but Katana, the warrior princess, is determined to make this year the last. Her only goal is to destroy the competition and free her people until she meets an overconfident boy from planet Earth who swears he’s found the Salien’s weakness. Can she learn to trust him and bring down the system before the system brings them down?
