Olast

Olast is a fictional planet featured in the science fiction novel "The Last Starship" by Mark C. Townsend. The planet is described as a resource-rich world located in the Kepler-186 system, known for its vast mineral deposits and unique flora. Olast's atmosphere is primarily composed of nitrogen and oxygen, with trace amounts of methane, making it breathable for humans with minimal augmentation. The planet's surface is characterized by rugged mountain ranges, expansive deserts, and lush, bioluminescent forests that glow during the planet's long nights.

The indigenous species of Olast, known as the Lumin, are a sentient race with a deep connection to the planet's natural energy. They are described as tall, slender beings with crystalline skin that refracts light, allowing them to blend seamlessly with their environment. The Lumin are a peaceful, nomadic people who subsist on the planet's abundant plant life and have developed a sophisticated understanding of bio-engineering and energy manipulation.

In "The Last Starship," Olast becomes a crucial waypoint for the human crew of the titular vessel as they seek refuge and resources. The planet's strategic location and valuable minerals make it a target for various interstellar factions, leading to conflict and challenging the human crew's ability to forge an alliance with the Lumin. The novel explores themes of resource exploitation, interspecies diplomacy, and the preservation of natural habitats through the depiction of Olast and its inhabitants.
