Thebani

Home to the jellyfish-like Noo'ru, Thebani is a gas giant of immense size, with breathable air at the upper "Tiers" but more and more toxic gasses with denser atmosphere the further down one v entures. Thebani "Cloud divers" wear protective suits and oxygen tanks in order to harvest the highly valuable gasses beneath which can be sythesized as industrial fuel. But divers must take caution, for the friendly Noo'ru are not the only inhabitants of Thebani and somewhere in the blackest clouds, something massive stirs.
