Vieneo is a terrestrial moon and the only natural satellite of Iomere, the fourth of six planets in the Yonmaran system.

A majority of the trade outposts and settlements have occurred near or on Vieneo. The moon is rich in atmosphere, liquid water, and minerals but is devoid of indigenous life. Vieneo is the only body meeting the United Stellar Republic's suitability criteria for a radius of approximately 70 parsecs

It is believed that Vieneo was once a moon of the planet Ostlon.

Name and etymology

Vieneo is named from the Swahili word (maeneo), meaning "province" or "extent of area".


Vieneo was discovered by Captain Ruben Evans (USV Flying Mast) on February 16, 2218 and was coincident with the discovery of the Yonmaran System. Vieneo was named in honor of the United Stellar Republic's claim and his Waswahili heritage.

Physical characteristics

Vieneo Landforms

Vieneo's surface is mostly high-density rock and inorganic compounds with only 13% of the surface covered in highly brackish water.

Plate Tectonics

Vieneo Plate Tectonics

The surface has patchwork regions of broken terrain indicating intense geological activity in the moon's past, and is crisscrossed by huge canyons. Approximately 70% of this was attributed to underground faults which caused rivers to change directions and create rigid changes in elevation.


Vieneo Earthquakes in 2242

Compared to Earth, Vieneo experiences less frequent quakes but with a higher magnitude on the order of 1 to 2 Richter units (10-100 times the energy output).
