A frigid world of ice, Polus orbited Avindia, a binary star within the Avindia system. This system resided in the Outer Rim Territories. This mountainous planet was characterized by a vast frozen ocean, frequent blizzards, and ice storms that regularly swept across its surface. The average day temperature was a chilling 50 degrees below the freezing point. Polus served as the homeworld for the Pyn'gani, a near-Human species.

With a diameter of 9,562 kilometers, Polus was located in the Avindia system within the Oricho sector of the Outer Rim Territories. This planet orbited the binary star Avindia, positioned between the trade routes of the Braxant Run and the Celanon Spur. Predominantly mountainous and arctic, Polus featured a single, enormous frozen ocean. Its average daytime temperature reached 50 degrees below freezing, accompanied by regular blizzards and ice storms. However, a brief seasonal warming occurred when the planet received light from both of its suns. A moon also orbited Polus, which was inhabited by Dral'k ice worms and various other aquatic creatures.
The Pyn'gani, a near-Human species, originated on Polus. They played a significant role in the development of carbon freezing, and mining was a major source of revenue for Polus. In 995 BBY, Anno Wen-Chii, a Pyn'gani Jedi Master, and his Padawan, Nalia Adollu, journeyed to the planet to research the evolution of life in the galaxy.
During 0 BBY, Polus served as a headquarters for the Alliance to Restore the Republic, equipped with a planetary ion cannon. It was subsequently attacked and seized by the Galactic Empire. Around 3 ABY, the Zann Consortium conducted a raid on Polus, enslaving the indigenous Pyn'gani population.
The Pyn'gani were native to Polus, a near-Human species. To survive the extreme cold of their homeworld, they protected their cities with heat generators. Carbon freezing was significantly advanced by the Pyn'gani, and they derived a considerable income from mining operations. Around the time of the Galactic Civil War, the planet's population was approximately 600,000. The primary language spoken was that of the Pyn'gani. While wary of outsiders, the Pyn'gani were interested in adopting new technologies.
