There are moments of calm at the front, but not for specialists waging an invisible, secret war. Having assembled a huge fleet, the Gayun Empire is capable of delivering a crushing blow to the Solar Union, which is not ready to repel it. Federation intelligence has developed a plan for waging psychological warfare on enemy territory. Create a mythical threat to an entire empire. Find allies in the ranks of ardent opponents. Delay the enemy's invasion by making him doubt his abilities. Reveal the most guarded secrets. Who is capable of this? All this can be done by three people: Shaman, Samum and Sorcerer. Their techniques are unexpected, sophisticated, rely on the enemy’s strength, turning it against him. Their methods are based on deep knowledge of psychology, wave energy, secret forces cultivated by clans of priests from other planets. Invisibles among the invisible. Those few who know about them call them nettras - specialists who solve the tasks assigned to them in an unconventional way.
