The Sun Runner was a 400 meter-long Corellia StarDrive Alpha-class heavy transport that went missing around 4000 BBY, when the Margrave Octan of the Darpa sector transported his family and 867 colonists to the Fondor moon of Nallastia, in the Tapani sector. Because the Margrave was a member of a ruling family known as the Royal Octans—which had obtained their wealth as space pirates—he carried aboard his ship three power gems that were able to disrupt magnetic defense shields. His ancestors had used these same power gems to overtake enemy ships and seize their property.
