Noxuna

Noxuna is the largest moon of Telossia. The moon is unusually massive for a terrestrial, starless world. Likely, it was cast out by from the edge of a nearby system several billion years ago until it was captured by Telossia.

The moon was also the sight of a duel between Ahrganot Skizgo and his brother Kaden Wezga. Shortly after, the first recorded appearance of Altus Infra since the Yallvus Revolution took place.

Orbit
Noxuna also tidally locked, but it is not completely dark. Telossia emits a dim red light which warms the dayside up to 50 °C, while the nightside dips down to -20 °C. Convection currents result in a modestly temperate region of around 32 °C at the twilight areas.

Telossia's gravitational pulls also stir tectonic activity on the surface. As a result, Noxuna is actively volcanic.

Atmosphere
Noxuna has a mixed atmosphere of nitrogen, neon and methane giving the sky a pale, red color. Noxuna's high density allows it to retain this atmosphere with an unusually high pressure, resulting in little temperature variance across the entire moon.

Dust storms on Noxuna are common due to temperature differences between the day and night sides.

Geography
Noxuna is a barren, rocky desert on the surface. Volcanic and tectonic activity has shaped the landscape into ridges, mountains. Several patches of black volcanic rock are scattered throughout the moon which are surprisingly recent, dating back only a few thousand years.

Noxuna has few caves due to the lack of liquid water on the planet. Such caves of Noxuna were formed from shifting tectonic plates. As a result, Noxuna is virtually lifeless save for a few extremophile microbes.

Colonization
While Noxuna is a poor candidate for colonization, Noxuna remains of scientific interest due to the presence of Omni ruins on the surface. In the past, these ruins were likely a military outpost in war with the Harbingers. Unfortunately, looters had picked the ruins clean long before any serious archeological expeditions could go beyond the planning stage.
