Pnornáki

Pnornáki is a fictional planet located in the Kepler-186 system, a star system approximately 500 light-years from Earth. The planet is characterized by its unique ecosystem, dominated by bioluminescent flora that illuminates the landscape during its extended twilight periods. The atmosphere of Pnornáki is rich in nitrogen and oxygen, with trace amounts of an unknown gas that contributes to the unusual hues of its sky, often appearing as a vibrant emerald green.

The indigenous lifeforms on Pnornáki are diverse, ranging from microscopic organisms to large, herbivorous creatures that feed on the glowing vegetation. A notable species is the "Lumiflora," a plant that emits light through a complex biological process, serving as the primary energy source for many of the planet's inhabitants. Several complex, sentient species are theorized to exist on Pnornáki, though direct observation and communication remain elusive due to the vast distances involved.

Exploration of Pnornáki has been limited to remote sensing and theoretical modeling. Initial data suggests a temperate climate with significant geological activity, including volcanic regions that release gasses essential for the planet's unique atmospheric composition. The planet's axial tilt causes distinct seasonal variations, impacting the intensity and patterns of bioluminescence across its surface. Further study is required to fully understand Pnornáki and its potential for harboring life.
