Charos

Charos, known in the old ages as Io, is the first Galilean moon of Letum.

Features
Charos is perhaps the most hellish of Letum's remaining moons. Its surface is littered with frozen sulfuric lakes and volcanoes, making any human re-colonization near impossible. Despite this, a few freelance researchers still come to this moon to examine its many life forms. Expanse Walkers are the most dominant forms of life, being mostly docile, yet clumsy creatures, that feast off of the moon's sulfur. Jovian Goliaths also have a major presence on Expanse.
