Quartri

Quartri is a fictional celestial body featured in the science fiction novel "The Chronicles of Xylos" by Anya Sharma. In the narrative, Quartri is depicted as a tidally locked planet orbiting a red dwarf star named Solara. Its surface is characterized by extreme temperature gradients, with one hemisphere perpetually facing the star and experiencing intense heat, while the other is plunged into eternal darkness and frigid conditions. A narrow habitable zone exists in the terminator region, where life has adapted to the twilight conditions.

The inhabitants of Quartri, known as the Lumina, are described as bioluminescent beings who have developed advanced technologies to harness energy from the red dwarf star and survive the harsh environment. Their civilization is heavily influenced by the planet's unique geological formations, including vast crystalline caves and geothermally active regions within the terminator zone. The novel explores themes of adaptation, resource management, and interspecies relations through the lens of Quartri and its inhabitants. The planet's lore also includes ancient prophecies and the lingering threat of solar flares from Solara, which shape the Lumina's societal structure and technological pursuits.
