Askold Rus 18+

Sergeant Askold Rus, after a mysterious anomaly, finds himself on an alien cascade — a giant station left completely deserted. With the help of the AI Inna and his mentor Dorin, he masters spacecraft piloting, advanced technologies, and combat skills. Gradually, he discovers that his comrades have been transported to another cascade in the Alpha Centauri system. Rus prepares a ship, acquires new knowledge, and establishes contact with Earth to transmit data and report on his mission. His ultimate goal is to find his comrades and return home, overcoming interstellar distances and technical limitations.
