Estooni

Estooni is a fictional planet located in the Andromeda Galaxy. It is known for its diverse and often extreme geological formations, shaped by a history of intense volcanic activity and rapid tectonic shifts. The planet's surface is characterized by vast obsidian plains, towering crystalline mountain ranges, and deep, phosphorescent caverns.

The atmosphere of Estooni is rich in sulfur compounds, giving the sky a perpetual, hazy orange hue. Temperatures can fluctuate dramatically, with scorching hot zones near geothermal vents and frigid regions in the shadow of its moons. Life on Estooni has adapted to these harsh conditions, with many organisms possessing silicon-based biology and the ability to withstand high radiation levels.

The dominant sentient species, the K'tharr, are a stoic, subterranean race that navigates the planet's underground networks. They have developed advanced geothermal energy technologies and a unique form of telepathic communication, essential for survival in their dark environment. The K'tharr are known for their intricate craftsmanship, particularly in the manipulation of crystalline structures.

Estooni's unique mineral deposits, including rare isotopes and highly conductive crystals, have made it a target for off-world exploration and resource extraction. However, the planet's volatile nature and the K'tharr's protective stance have made sustained colonization efforts difficult. The planet remains a subject of scientific curiosity and a testament to the resilience of life in extreme environments.
