Darkness is a friend, an ally. Darkness allows us to understand others, to see what they value when they believe no one else is looking. It allows us to be honest with ourselves, to express those values that we would disavow in the light. The light blinds us. It is only in the dark that we see clearly, and there is a great dark hidden among these worlds.
―Darth Rivan

Darth Rivan was a Zelosian male who was a Sith Lord during the time of the New Sith Wars, having taken his Sith name from a corrupted Sith manuscript which identified Darth Revan, the Dark Lord of the Sith who was redeemed during the Jedi Civil War, as "Rivan."

During the New Sith Wars, Darth Rivan visited the uncharted Cularin system and settled on the planet Almas, despite this world's inhospitable atmosphere. There, he built a fortress, intending to delve in the mysteries of the dark side.
