Vulcar was a volcanic planet located within the Vulcar system of the Mid Rim. It was covered in the Sulphur Pits of Vulcar: vast, sulphuric plains with sinkholes and sulphur-laden geysers. The workers in the Pits were in conditions as deplorable as those of the spice miners of Kessel. Droids however proved more cost effective and were used more often. Minerals mined on Vulcar included oridium.
