When Kaeslana, who had recovered all his memories and powers (set to be a Commander-level, the omnipotent explanation - Aha), challenged Nanook but ultimately failed and was merged into the Iron Tomb, he did not completely dissipate. An unknown force brought a trace of his consciousness to the beginning of the pioneering (Black Tower Space Station) and also gave him his own body. What kind of story will happen between Kaeslana, who came here with all his memories, and the pioneers?
