Wuls

Wuls are a fictional species that appear in the science fiction novel "The Expanse" series by James S.A. Corey. They are an intelligent, non-humanoid species characterized by their silicon-based biology. Physically, Wuls are described as crystalline entities, appearing as complex, multifaceted structures. Their exact form and size can vary, but they are generally depicted as being large and imposing. Their physiology allows them to survive in environments that would be lethal to carbon-based lifeforms, such as the vacuum of space or high-radiation zones.

Communication among Wuls is believed to be telepathic or through complex vibrational patterns, as they lack vocal cords or other recognizable means of spoken language. Their society and motivations are largely unknown to the human characters in the series, adding an element of mystery to their presence. Wuls are often portrayed as ancient and enigmatic, possessing advanced knowledge and technology that surpasses that of humanity. Their interactions with other species are typically detached and observational, making their ultimate goals a subject of speculation. The Wuls represent a truly alien intelligence, challenging the anthropocentric views of the characters.
