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.
