Cellin

Cellin is a natural satellite of Crusader. The moon is volcanically active and has (at least) "100 volcanoes".

"Named after the youngest of the three siblings featured in the 24th century children's morality tale, 'A Gift for Baba,' this moon features over a hundred currently dormant volcanoes that are said to represent Cellin's simmering anger."

"Burning with volcanic activity, Cellin is the counter to her icy sister. Although the volcanoes have been dormant for hundreds of years, the surface is dotted with thermal geysers that erupt without notice. The largest of such geysers can destroy heavy vehicles. Highly corrosive clouds of gas are regularly released from the moon's surface, creating low visibility and damaging anything caught outside."

Phillip Xu built the first permanent homestead on Cellin in 2906.

On 2904-10-02, Chad Fawley completed the first successful solo circumnavigation of Cellin in a ground vehicle.

Atmospheric Composition
Cellin has an extremely thin and toxic atmosphere, rendering it unbreathable. However, the presence of trace amounts of oxygen allows pressure suits to extract breathable O2 from the environment.
