Kalarba was a pleasant and largely undeveloped world near several powerful and rich Mid Rim systems. The planet was covered in a large world-spanning ocean and the landmasses were dominated by mountain ranges including the Three Peaks of Tharen and rocky coastlines. Because of its undeveloped beauty, the planet greatly profited from tourism.
The native vynock was a silicon-based lifeform which flourished in planetary atmospheres in contrast with its cousin the mynock which lived in space.
Though one of its moons, Hosk Station, had been settled during the early years of the Galactic Republic, Kalarba was only settled during the last centuries of the Republic. The descendants of these colonists have since developed a high opinion of self worth and a great strength of spirit which is said to be embodied within the Three Peaks of Tharen, a widely-visited mountain range near the planet's equatorial zone.
In 22 BBY, Kalarba was one of ten Mid Rim planets that loosened immigration restrictions to allow for the resettlement of beings displaced by the Separatist Crisis.[3] The planet was located within Separatist space during the Clone Wars.[2] During the Imperial Period, Wena served as its governor.
