Starfleet has received a communication from a servant of one of the Klingon great noble houses. She claims to have vital information about the Klingon's war plans, and she is willing to exchange that information for relocation to a planet out of the empire's grasp. Go to the trading station in orbit of Argelius II and find Marta. She'll be waiting for you there. That area is a hotbed of illicit activity, [Your rank], so be on the lookout for smugglers. Proceed to the Treasure Trading Station in the Argelius Sector and locate Marta, a defector from the Klingon Empire.
