2182. Earth civilization emerged from the cradle and spread its influence over a large number of star systems.
An entire galactic Empire was formed. Military spaceships armed with beam and nuclear weapons patrolled the borders and protected the Empire from outside invasion. Until new, previously unknown enemies appeared - the Klesians.
The Klesians possessed not only powerful weapons, but also unique superpowers - psi-abilities. The Imperial army suffered defeat after defeat. Soon the battles approached the solar system.
The Imperial command decided to begin searching for people who also possess psi-abilities close to the Klesians. Four volunteers were found who agreed to undergo training and help in the defense of Earth civilization from the Klesians. One of them is you.
