In a universe where the homeworld of humanity is lost to legend, countless human civilizations thrive on distant planets, some isolated for millennia. Among these "Darkworlds," cut off from interstellar infonets, lie secrets that could reshape the cosmos. Captain Ji-eun Moon commands an exploratory mission from Earth, embarking on a journey that shifts course upon detecting ancient radio signals from a distant star system. What they discover is beyond imagination: a planet teeming with advanced technology, millions of humans, and alien allies known as the Sulivans, who resemble creatures from a child's dream. As they navigate this new world, the explorers encounter the Yonohoans, descendants of Neanderthals who share a unique bond with the Sulivans. At the center of this cultural exchange is Eolai, a Yonohoan with a fascinating outlook on life and a mission to bridge the gap between species. His world, shaped by temporal mechanics and ancient customs, challenges everything the Earthlings thought they knew about humanity's place in the universe. Darkworlds weaves a tale of exploration, cultural clash, and unexpected alliances. As Captain Moon and her crew delve deeper into the mysteries of the Yonohoans and Sulivans, they must confront their own preconceptions and uncover the truth behind the enigmatic signals that brought them here. Join the journey in Darkworlds, where every discovery raises new questions, and the line between ally and adversary blurs in the vast expanse of space.
