Arkania
Arkania is a tundra world in the Colonies region. It is covered by diamond pits where miners extract melon-sized gems from the planet's crust. Jedi Master Arca Jeth established a Jedi training outpost in the wilderness of Arkania some 4,000 years BBY. Centuries ago, the scientifically-minded Arkanians began cyber-enhancing the brains of their primitive neighbors, the Yaka. Soon the stocky Yaka were one of the most intelligent and quick-minded species in the galaxy, with a bizarre sense of humor to match. Animal life on the planet includes the Arkanian dragon and the Arkanian jellyfish.
