Gazzari is a rocky and mountainous planet with long stretches of shallow seas and vast polar caps dotted with magnificent, towering glaciers. While the planet is considered temperate, the altitude of the extensive highlands leads to lower temperatures, generally speaking, while the equatorial region has the weather and climate that most would expect under the term "temperate". The equator is a land of marshlands and idyllic plains of rolling hillsides and prairies, and thus has attracted most of the planetary population. Yet the world is not inherently peaceful. Earthquakes are a daily occurrence due to high tectonic activity across the globe, with much of the world's urbanisation specifically adapted to these violent conditions.

Much of the rocky terrain is inhabited by a native sub-species of hawkbat, which has thrived in its environment after being introduced to the planet at some time in its history. Additionally, the vast mountain ranges are the domain of creatures both large and small which are accustomed to life at high planetary altitudes, with the most notable being the d'oemir bear. Nerfs and akk dogs live off the tall grasses of the prairies and hillsides along the equator, while the marshes are home to fauna, like the terrifying arachnid kryknas, or the companionable kaadus, originally native to Naboo. However, until modern technology in the form of numerous ester converters was able to significantly mitigate the corrosive effects of the downpours, all of these lifeforms struggled to cope with the acid rain that the world's surface was subjected to on a regular basis. As a result, a specific sweet scent is ever-present in the air across the entire globe.

The planet was surveyed during the Old Republic era, roughly two millennia prior, and was settled by the Humans from the nearby Seswenna sector during what was known as the Republic Dark Age. At that time, Gazzari was located along the frontier between two rival Sith states that each claimed a portion of the local interstellar neighbourhood. As a result, a major battle had been fought in orbit of the planet and on its surface by the two enemy Sith Lords, who later joined forces against a third Lord of the Sith, who had orchestrated their rivalry and conflict from the shadows. In the centuries that followed, Gazzari remained in Republic space and attracted a diverse and colourful population from the Mid and Outer Rims.

A sizable proportion of urban population centers have been built along the equator, where the climate is the most pleasant and temperate. It became a well-developed and civilised world over the centuries, and attracted various forms of industry to its surface and orbit, as the planet developed economically. Today, it is a loyal and active member of the interstellar government that administers the Garis sector.
