Kaledus is a fictional planet featured in the science fiction novel "The Serpent's Eye" by A.J. Klein. The planet is characterized by its unique bioluminescent flora and fauna, which illuminate the otherwise perpetually twilight world. The dominant sentient species on Kaledus are the Lumina, a silicon-based lifeform that communicates through intricate patterns of light emitted from specialized organs. Their society is deeply spiritual, revolving around the reverence of the "Great Luminary," a celestial body that, according to their beliefs, provides life and guidance.
