valkion

Valkion is a fictional species featured in the science fiction novel "The Expanse" series by James S. A. Corey. They are an ancient, non-humanoid alien race that existed millions of years before humanity. Valkion are known for their advanced technology and their role in the creation of the protomolecule, a complex biological agent that drives much of the series' plot. Little is known about their physical appearance or their ultimate fate, as they are only encountered through remnants of their civilization and the technology they left behind. Their existence is primarily inferred from archaeological discoveries and the effects of their creations on other species. The Valkion are depicted as having been a highly intelligent and technologically sophisticated species, capable of manipulating matter and energy on a cosmic scale. Their motivations and societal structure remain largely a mystery, adding to the enigmatic nature of their legacy. The protomolecule, their most significant legacy, is a tool that facilitates rapid evolutionary change and terraforming, but it also poses a significant threat. The series explores the implications of encountering such advanced, ancient technology and the potential consequences for younger civilizations.
