Oshan
Valyr and Oshan, as seen from an observatory on Mesbin.
Name: Oshan
Designation: Kaywell Af I
Discovery (Mesbin): Naked Eye Observations.
Oshan was the first satellite of Valyr to be discovered, and the only one to be discovered non-telescopically. Oshan is bright and reflective, but so close to Valyr that it is usually hard to tell one apart from the other. It was discovered by Chriswayan Kerman, famous fictional world-builder and eccentric amateur astronomer. After conclusively determining that Oshan was in fact a satellite of Valyr, he purchased a large telescope in an attempt to observe the satellite. What he--and many astronomers after him as well--found, was a white world with dark spots of a reddish-brown color. He supposed that these were oceans of some reddish volatile fluid floating on a bright icy moon. Other astronomers proposed that it might be huge continents drifting across a frozen ocean--giving rise to Oshan's name.
