Otunia II is a gas giant planet that is the largest planet in the Otunia system. Its main export is Tibannagas, and it is home to many species of creatures that inhabit typical gas giant worlds such as Purrgil and Streaked Velker. When viewed from space, the atmosphere consists of hues of red, orange, and tan-colored gases, but these can change depending on the wind patterns and various denser gases that are stirred throughout the atmosphere.

This world was discovered by several different corporate exploration teams and was initially set up as a mining colony. As such, various factions competed for ownership of these resources and the planet over the centuries. The legacy of this conflict is most often seen in the various settler cities that consist of large living complexes with minimal amenities outside of places to sleep and eat, although various frontier-style entertainments such as saloons and bars have managed to set up shop away from the prying eyes of the local authorities. Despite the spartan living conditions, through the ages, Otunia II has been colonized and inhabited by various settlers looking to seek their fortune in the Outer Rim.

More recently, there has been a concerted effort to develop a bounty-hunting sector and various factory cities that produce a variety of ships, vehicles, items, and droids that are used for local purposes but also allow for export to other systems throughout the galaxy. These recent additions to the planet allow the governing body to further enhance the commerce of this gas giant. As a result of this mixture of cultures and civilizations, there is an eclectic mix of various building types and styles that match this frontier settlement mentality. As a result of this cultural mix, the facilities often take inspiration from various civilizations, such as Coruscanti skyscrapers, cantinas that can be found on planets such as Tatooine, or through Kaminoan architectural norms.

For a planet that is close to its single sun, a circadian rhythm of 27 hours and a year of 300 days provide daily rhythms that are familiar to many sentient species. As such, residents of Otunia II have adapted to the planet's rhythm by following a 27-hour sleep-wake cycle. They divide their day into three segments: nine hours of work, nine hours of leisure, and nine hours of sleep. However, many corporations push their workers to spend long hours in the gas mines and refineries in order to boost production numbers, and it is rare that workers get to enjoy the full nine hours of either sleep or leisure time.
