1. The Galaxy

Water Tribe: Humanoid. Common characteristics include darker skin, blue eyes, and dark hair. Low-level empathic ability; rarely, healing ability. The Water Tribe are generally a compassionate race, but they are capable warriors as well. There is a hierarchy of clans within the tribe, with each clan leader answering to the tribal chief. The current Water Tribe chief is Hakoda.

Ba Sing Se Cluster: The area known as the Ba Sing Se Cluster is made up of an amalgam of species, including the Oma, the Shu, the Chong, the Zhang, and the Gan Jin. All these peoples are hardworking, industrious, clever, and inventive. The Ba Sing Se merchants carry the finest goods in the galaxy and shipping is the majority of their industry. However, the quality of goods and number of ships carrying them makes the cluster the main target of space pirates. The Ba Sing Se Cluster is ruled by elected parliament.

I. Oma: Humanoid. The Oma are the most populous species in the Cluster, occupying most of the member worlds. The Oma vary in appearance, due to interbreeding with both Water Tribe and A'pa. Most Oma have green eyes (varying shades), however, and under no circumstances would you ever find a hairless Oma, A'pa heritage notwithstanding.

II. Shu: Humanoid. The Shu are the second-most populous species in the Cluster, and cohabit peacefully with the other races. The Shu are made of living stone, which varies in hue, and are tremendously strong; most Shu can lift around five times their body weight.

III. Chong: The Chong are semi-nomadic, catlike humanoids with a fondness for music and - famously - parties. While sometimes hard to take seriously, the Chong often have a unique way of looking at situations, and are therefore valued in the Parliament.

IV. Zhang: The Zhang are small, furry, bearlike creatures of… questionable intelligence and great ferocity that are always clothed in varying shades of purple. They have been involved in a blood feud with the Gan Jin for time immeasurable, and can always be counted upon to be as contrary as possible - unless they think it will harm the Gan Jin, in which case they are all for it. The rest of the Parliament just puts up with them.

V. Gan Jin: Nearly indistinguishable from the Zhang, the only real physical difference between the two is the Gan Jin's love of the color green, instead of purple. They are every bit as fierce as the Zhang, but are more active in the Parliament and seem to be able to be able to overlook their hatred of the Zhang for brief periods of time.

Agni Kai: Humanoid. The Agni Kai are an extremely territorial race that inhabit several planets along the outer rim of the galaxy, known for their fierce aggression when provoked. Agni Kai are fair-skinned, with amber or gold eyes and dark hair. Their government is a monarchy, ruled by the Fire Lord, who is also the supreme commander of the sizable military - in fact, it's the largest in the galaxy. All Agni Kai citizens are required to serve three years (at a minimum) in either the army or the Armada. The Agni Kai have a strict code of honor both on the battlefield and off of it, and while they are fearsome opponents, they will never do anything that violates this code of honor, such as killing civilians or unarmed combatants, maltreatment of prisoners, or torture. Agni Kai fight duels often; if a slight to their honor is perceived, they are quick to amend the situation on the field of battle. Perhaps as a result, Agni Kai healers are second only to those of the Water Tribe.

A'pa: Humanoid. The A'pa are fair-skinned and slender. They are hairless, but adults (age 16 and above) sport interconnected blue arrow tattoos on their heads, arms, and legs, the symbolism of which is known only to them. They are a naturally curious people, and are most often found on starships as navigators, exploring the galaxy. The A'pa are traditionally allied most closely with the Water Tribe. They are mostly group wanderers, with no real government, and if there is an A'pa homeworld, it has long been forgotten.
