Eralam was a type of lightsaber crystal once mined on the third moon of the planet Erai, though orbital bombardments by ancient Sith forces against the moon made them very rare. If they could be found, Eralam crystals produced a clear, superior lightsaber beam. Its mineral form was known as eraladium.
In Star Wars: Knights of the Old Republic, the crystal is listed as having +2 attack and +2 damage.
