Otrus

Otrus is a fictional planet located in the Andromeda Galaxy. It is known for its unique geological formations, characterized by towering crystal spires that reach into the atmosphere. The planet orbits a binary star system, resulting in dramatic shifts in light and temperature throughout its day-night cycle. The native flora of Otrus has adapted to these extreme conditions, often displaying bioluminescent properties.

The dominant sentient species on Otrus are the Lumina, a silicon-based lifeform. The Lumina are known for their telepathic abilities and their deep connection to the planet's crystalline structures. Their society is structured around communal living and a profound respect for the natural environment. They have developed advanced technology that draws energy directly from the planet's geothermal core and the light of their twin suns.

Exploration of Otrus by off-world species has been limited due to the planet's remote location and the Lumina's cautious approach to outsiders. Initial encounters have been peaceful, with trade focusing on rare minerals found on Otrus and specialized Lumina artifacts. The planet's atmospheric composition is breathable for many humanoid species, though its lower gravity can be disorienting. Further study of Otrus and its inhabitants is ongoing, with a particular interest in understanding the Lumina's unique biology and their planet's unusual geological phenomena.
