Quainaar

"The land of deals and the land of fun, this is Quainaar, the beautiful world of the frozen sun"
-Tzan'Kai in his book The Planets of Mastaar
Quainaar is a planet located in the eastern core region of the Mastaar Galaxy. It is known officially as The Free World of Quainaar, and it's codename is Diplomacy. Quainaar is known for being a meeting place between nations, a place where they can figure out their differences, most recently Aravaraia, Harvath, and Earth. 
Quainaar's capital city is Quinnopolis, located next to the Glass Ocean in the equatorial part of the planet. The world's primary native species are the Quainaa, strange, boneless creatures that remind of amoeba. They prefer to take humanoid forms, but can shape shift as much as their squishy bodies allow. 
Due to the relative peace Quainaar earns as a result of its diplomatic clout, it has no need for a military, and instead simply has a peacekeeping police force.
Quainaar is a world of impossibility and apocalypse. It is located on the outer edge of its star's habitable zone, making the planet freezing cold. Despite that, life on the planet has evolved in abundance, and in turn it is known as the "frozen jungle". It wasn't always like this though. The planet was once a scorched wasteland that orbited a red giant, but when its star died and shrunk to become a white dwarf, the planet fell into its habitable zone, after which life emerged. 
The planet also suffered a massive cataclysm when a rouge planet struck its moon Twinstaar, causing it to fall towards the planet. It destroyed much early life, and then broke into a ring system. It was during this time that the quainaa evolved. Many quainaa myths circle around the fall of the moon. The most popular states that the early quainaa angered the sun, Onestaar, which flung a rock to destroy all life, but Twinstaar gave its life to protect the people of Quainaar, and its rings are a shield that it uses to protect the planet to this day.
