Proteus

Like the hanar homeworld, Proteus has more than 90% oceanic cover. The incredible heat thrown off from Athens raises global humidity to 100%, creates constant cloud cover, and powers colossal typhoons that rage across the surface year-round.

Hot, humid, and storm-wracked, Proteus' rare combination of oxygen-nitrogen atmosphere and carbon-based biosphere nevertheless recommend it for colonization. A pilot program is studying the possibility of colonies below the ocean surface, safe from the worst effects of the weather.
