Heglark Ress was a mole in the Imperial Remnant, working for the New Republic. During his operations, he managed to gather technical data on the Imperial campaign known as Operation Dark Disease. However, he was discovered by the Imperial Security Bureau and was stranded on Corellia while trying to escape. There, he contacted Jedi Master Kyle Katarn, who found Ress in Coronet City. After escaping two ambushes by mercenaries, they eventually made it to Coruscant, where Ress' information on Operation Dark Disease was sent to new Republic Intelligence.
