Vieneo is the moon of Iomere, one of six planets in the Yonmaran system situated about 225 light-years from Sol (Earth).
Vieneo, named from the Swahili word (maeneo), meaning "province" or "extent of area") is the only natural satellite of Iomere and the only body meeting suitability criteria for a radius of approximately 70 parsecs.
It 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.
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 completely devoid of indigenous life. It is believed that Vieneo was once a moon of the planet Ostlon.
Physical characteristics
Vieneo's surface is mostly high-density rock and organic compounds with only 13% of the surface covered in highly brackish water. The surface has patchwork regions of broken terrain indicating intense geological activity in the moon's past, and is crisscrossed by huge canyons.
