Sekavs

Sekavs are a fictional species featured in the science fiction novel "Children of Time" by Adrian Tchaikovsky. They are an insectoid species, resembling large spiders, who have evolved a complex society and advanced technology. The Sekavs are characterized by their eight limbs, chitinous exoskeletons, and the ability to communicate through a combination of pheromones and rapid vibrations of their limbs.

In the narrative, the Sekavs are the dominant intelligent species on the planet of the same name. They have developed a hierarchical society with a strong emphasis on collective good and scientific advancement. Their technological progress has led them to develop sophisticated tools, architecture, and even space travel capabilities, though their methods and understanding of the universe differ significantly from human perspectives.

The Sekavs' evolutionary path has instilled in them a pragmatic and often ruthless approach to survival. They are depicted as highly adaptable and resourceful, capable of overcoming significant environmental challenges. Their societal structure and biological makeup influence their interactions with other species, including the human protagonists of the novel, leading to complex and often tense encounters. The Sekavs represent a unique example of non-humanoid intelligence and societal development within the science fiction genre.
