An idyllic world close to the border of the Outer Rim Territories, Naboo is inhabited by peaceful humans known as the Naboo, and an indigenous species of intelligent amphibians called the Gungans. Naboo's surface consists of swampy lakes, rolling plains and green hills. Its population centers are beautiful -- Naboo's river cities are filled with classical architecture and greenery, while the underwater Gungan settlements are a beautiful display of exotic hydrostatic bubble technology.

In its earliest ages of civilization, Onderon was a world marked with savage jungles that were filled with dangerous creatures. To survive, the primitive human inhabitants of the planet protected themselves behind the walls of fortified settlements. Over time, these grew to become enormous walled cities, like the planet's capital, Iziz. In the modern era, during the time of the Clone Wars, the planet's monarch King Sanjay Rash allied Onderon to the Confederacy of Independent Systems. Many Onderonians, however, refused to recognize the legitimacy of Sanjay's rule -- they preferred the neutral stance championed by former monarch Ramsis Dendup, whom Rash ousted.

The Gungans are the native inhabitants of the planet Naboo, an amphibious species with hardy lungs capable of holding breath for extended periods. Their skeletal structure is extremely flexible, as it is made of cartilaginous material rather than hard bone. The long Gungan face has a tough yet flexible bill for burrowing and rooting out food. They have long muscular tongues with which they scoop mollusks and lesser amphibians from the Naboo swamps. While most spacefarers would dismiss Gungans as primitives, they have developed an advanced technology.

The stout and stern leader of the Gungans, Boss Nass was a proud keeper of his people's ways. His booming voice issued decrees on behalf of all the Gungans of Otoh Gunga. He kept a tight rein on Gungan affairs, continuing a longstanding custom of isolationism. Though Nass' temper is short, displays of courage and humility can pierce through his preconceptions. When Queen Amidala prostrated herself before the Gungan leader to request his aid in fighting off the Trade Federation invasion, he was impressed. Nass committed the Gungan Grand Army to wage war against invading battle droids.

A young native of Onderon, Steela and her brother Saw were members of the insurgency that opposed the rise of King Sanjay Rush, and Rush's alignment of the planet to the cause of the Separatists during the Clone Wars. Not as boisterous or as outspoken as her brother, Steela was nonetheless firmly dedicated to the cause of Onderonian independence. She was not one for impassioned speeches or political rhetoric. These were not her areas of expertise, and she felt far more comfortable peering through the macroscope of her blaster rifle. A crack shot, Steela racked up an impressive number of droid kills with precise headshots fired from the cover of canopy jungle.

The son of Separatist Senator Mina Bonteri, Lux was young, idealistic, and skeptical of the aims of the Republic and the Jedi Knights. His father was a fervent supporter of the Separatists, and was killed by clone troopers on Aargonar. Lux did not know what to make of Ahsoka Tano and her visit to Separatist space. After a failed peace overture begun by Mina extended to the Republic, Lux’s mother died, assassinated on Count Dooku’s orders. After making an ill-fated effort to avenge her by killing Dooku, Lux joined the anti-Separatist resistance on his homeworld of Onderon. After the rebels defeated the Separatists, Lux became Onderon’s Republic Senator.
