Alan deploys an escape pod to the planet alone and begins his quest for survival. To his surprise, he discovers a thriving human civilization on the underdeveloped planet whose genetic code closely mirrors his own. Despite being thrown into a world of swords and magic and feeling disoriented, Alan attempts to assimilate himself with his new comrades and make the most of his situation by using the symbiotic nanomachines [Nanom] within his body.
As Alan adjusts to his new surroundings, he wonders about what he will accomplish in this unfamiliar world. Prepare for a medieval sci-fi fantasy adventure!
