Koba (singular and plural) are simple, somewhat dim-witted creatures, quite primitive by most standards, yet quite passive and gentle as opposed to savage. They stand between five and six feet high, though their bulky frames make them quite heavy for their size. Males and females look almost identical; they have little use for clothing or armor. Koba have slightly wet-looking skin as opposed to scales, usually a drab olive green with lighter markings. Their upper bodies are narrow, tapering to heavy haunches, powerful legs, and large, webbed feet. Koba are good swimmers, though they prefer a medium between land and water, such as mud and swamp. Unlike reptiles, koba give birth to live young. They communicate through simple patterns of high-pitched chirps and whistles, and hiss loudly when angered.

        Koba have little need for the trappings of 'society'. Though not exactly animalistic, they derive much more from the natural world than they ever could from civilization. They move in small, nomadic tribes, inhabiting caves or ruins as opposed to building anything. Koba are pure herbivores, and thus have no need for even the most basic hunting weapons. If they carry or wear anything, it is generally something they've found. The saurians tend to be somewhat shy and naive, but are easily amused or bribed by offerings of shiny trinkets. They have a herd mentality, and tend to be very patient and tollerant of each other. They generally attempt to solve problems without violence, though their tempers can get the better of them, especially when they're forced to deal with rules and limitations they don't understand.

        Koba are not impressed by the thought of wealth or power. They are quite content and genuinely good-natured people, though their limited intelligence can make them hard to deal with. They tend to be rather afraid of certain magic or technologies at first, though they seem reasonably capable of adapting. If anything, koba are incredibly sturdy, stalwart companions, with an almost unbelievable loyalty to those close to them. They can be quite affectionate and playful at times, frequently breaking things in the process. This is a sort of natural clumsiness, perhaps one of the reasons they don't carry or wear much. Koba can also tactless at times, lacking the usual social restraints when expressing their anger, passion, or frustration.

        Essentially, the koba have no government. Most don't even understand the fundamentals of trade or warfare, and their scattered tribes do not have an organized backbone of any kind. Even at the tribal level, the koba have few desires other than to live and eat in peace. Most of their territory is swamp and wetland, environments that many of the other races find intollerable, and if it weren't for the fact that they make excellent work slaves, they would be left alone. Recently, however, the koba have started learning who their chief aggressors are by uniform and smell, and have taken sides with anyone opposing them whenever the opportunity has arisen. They are on good terms with the lutrai, as the two species frequently share territory and similar peaceful lifestyles.
