Vieneo, named from the Swahili word (maeneo), meaning "province" or "extent of area") is the only natural satellite of Iomere and the only habitable body 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 and minerals and is able to support a variety of life, though no indigenous beings have been found. It is believed that Vieneo was once a moon of the planet Ostlon.
Vieneo's surface is mostly high-density rock and organic compounds with only 9% of the surface covered in highly salinic water. The surface has patchwork regions of broken terrain indicating intense geological activity in the moon's past, and is criss-crossed by huge canyons.
