Cedonia Teraan was a Human female who belonged to House Teraan. In addition, she served as the Herald of the Gold Aurora during the era of the Cold War.
Cedonia and her brother, Lenn Teraan, became the last surviving members of House Teraan amidst the Great Galactic War fought between the Galactic Republic and the Sith Empire. This occurred when their house was decimated during a conflict with House Baliss, which led to them seeking refuge with House Organa. Subsequently, House Baliss seized control of their ancestral property.
In 3643 BBY, Cedonia and Lenn Teraan hired a smuggler to secretly enter their former estate. Their goal was to retrieve information from their home's library regarding the unlocking of an old droid that held the key to restoring their family's status. After the droid was unlocked, it revealed that many families were in debt to House Teraan for credits. The siblings then left to meet with the Royal Council to confirm the data.
Later, the Teraans once again sought the Voidhound's assistance. This occurred after House Baliss discovered the smuggler's intrusion and dispatched Xin Baliss to challenge Lenn to a death match. Fortunately for the Teraans, the smuggler accepted the challenge and succeeded in defeating the supposedly invincible duelist, Xin. Although impressed by the smuggler's abilities, the Teraans decided to leave Alderaan to avoid further attacks from House Baliss.
