Eralam Eralam represented a class of lightsaber crystal that, in the past, was mined from the third moon orbiting the planet Erai. However, these crystals became exceedingly scarce due to orbital bombardments inflicted upon the moon by old Sith armies. When discovered, Eralam crystals enabled the creation of a sharp and high-quality lightsaber blade. The mineral form of this crystal was referred to as eraladium.
