Vellaris

Vellaris is a fictional terrestrial planet in the Vellarian System, orbiting a mid-type star. It is home to the Vellari, a sapient species closely tied to a bioluminescent flora that illuminates many nocturnal landscapes. The planet is described as temperate with rich biodiversity.

Geography and climate: The surface includes forests, plains, wetlands, and archipelago coastlines. Two natural satellites produce pronounced tides and persistent night illumination. The climate features distinct wet and dry cycles with regional variation.

Life and ecology: Luminescent mosses, glow-cap trees, and a network of pollinators support a diverse ecosystem. Fauna ranges from herbivores to apex predators, many adapted to canopy or wetland niches. Conservation remains central to Vellari policy.

History and society: Indigenous Vellari organized into coastal city-states. A regional council emerged in the medieval-to-modern era, shaping infrastructure, education, and intercity cooperation. Modern governance emphasizes local autonomy within a framework of mutual defense and scientific collaboration.

Culture and science: Vellari culture centers on astronomy, horticulture, and craft traditions. Knowledge is transmitted through oral and written records, with a strong emphasis on observations of the night sky and seasonal cycles.

Economy and technology: The economy is primarily agrarian, with expanding ecological engineering, renewable energy, and small-scale manufacturing. Research in plant genetics, soil restoration, and sustainable farming methods is a distinctive feature of Vellari institutions.

In fiction: Vellaris appears in speculative fiction and tabletop settings, with varying depictions reflecting authors' world-building, but consistently portraying a society closely linked to its luminous environment.
