Felsisissa

Felsisissa is a fictional celestial body appearing in the fantasy novel "The Crimson Star" by author Lyra Blackwood. Within the narrative, Felsisissa is depicted as a planet located in a distant galaxy, characterized by its unique geological formations and a pervasive bioluminescent flora. Its atmosphere is described as a rich blend of nitrogen and oxygen, with trace amounts of an unknown gas that contributes to the planet's distinct coloration, often appearing as a swirling tapestry of emerald and sapphire from orbit.

The surface of Felsisissa is dominated by vast, crystalline deserts and deep, phosphorescent oceans. These oceans are teeming with a variety of aquatic life, many of which exhibit their own luminescent properties, creating breathtaking underwater displays. The plant life on land is equally remarkable, with towering, glowing trees and intricate, light-emitting fungi carpeting the landscape. These plants are said to pulse with a gentle rhythm, providing a constant, ethereal light that illuminates the planet even during its long nights.

Felsisissa is home to a sentient species known as the Lumina. These beings are described as having a deep connection to the planet's natural energies and are masters of manipulating light and sound. Their civilization is integrated with the environment, with their structures often grown from living matter and illuminated by the planet's natural glow. The Lumina are portrayed as a peaceful and wise race, with a profound understanding of the cosmos. The Crimson Star itself is a significant plot device in the novel, its proximity to Felsisissa influencing the planet's climate and the Lumina's culture.
