Dician, a female Human, was a Sith Lord and member of the One Sith, serving at the time of the Second Galactic Civil War. In 40 ABY, before the One Sith had revealed themselves to the galaxy, Dician acted as an agent operating away from the Sith world of Korriban. While doing so, she used a number of cover identities in order to hide her true affiliation from outsiders.
