xenna

Xenna is a fictional planet in the Sciarium galaxy created for speculative fiction and role-playing campaigns. It orbits the G-type main-sequence star Tethra in the Solis cluster. The planet is Earth-sized and features a 28-hour day, an axial tilt of 22 degrees, and a climate that ranges from temperate coasts to arid interiors, supporting multiple biomes.

Its geography comprises three major continents—Arion, Vespera, and Khelar—and extensive coastal archipelagos separated by the Azure Sea. The terrain ranges from temperate coastal regions to arid plains and high mountain ranges, including the Highcrest and Iron Spine Ranges, with several large rivers feeding delta systems.

Xenna was first contacted by spacefaring explorers in 2145, when the starship Argosy detected signals from the southern continent. Colonization proceeded over the following decades, culminating in the formation of the Arcadian Union in 2167 and the Unity Accord of 2260, which established a federated government and reduced interregional conflicts.

Xennan society is diverse, with multiple species and cultures coexisting under a constitutional framework. The official language is Xenari, a lingua franca developed from regional tongues, while local languages remain in use. Governance operates as a federative council system, with regional councils and a capital at Lumen City.

The economy blends agriculture, mining, and high-technology industries, including fusion power, autonomous logistics, and starship engineering. Xenna maintains a network of orbital facilities and interplanetary trade routes, and emphasizes ecological stewardship, scientific research, biodiversity preservation, and climate monitoring.
