Xiratha is a planet located in the Ursa Galaxy near the tip of the Little Dipper light-years away from earth. The planet’s green hue derives from large malachite crystal deposits covering its surface. The crystals give Xirathians special powers such as precognition, extrasensory perception (ESP), the power to heal, and other abilities based on their character. Xirathians are peacekeeping humanoids responsible for maintaining harmony and peace among the planets within the Ursa Galaxy and beyond. Initially from the planet Dubhe, the humanoids ruled there for five thousand years until their planet fell under the invasion of the Dark Chis (alien creatures that travel celestial bodies to destroy life on planets and consume their natural resources). The humanoids fled Dubhe and landed on Xiratha, gaining superpowers from the planet’s mystical green malachite crystals. Emperor Norcemo, leader of the Ursa Defense League (UDL), created new weapons powered by the green crystals to kill the Dark Chis. Then, he trained a unique team of agents; Eris, Firebird, and Star Angel,  on alien combat skills and armed them with specialized weapons to kill the alien creatures. After training his new agents, Emperor Norcemo sent Eris to earth to protect the humans from an attack by the Dark Chis.
