Aorali Ventirri

The enigmatic Ghostling Sith named Aorali Ventirri was one of Velok's instructors and a contemporary of Darth Plagueis, though the two never met and may never have known about each other.

History
Ventirri never spoke of her past during her two and a half years as Velok's Master. When he killed her he had no idea where she had come from, who had trained her, or what Sith splinter group she embodied. Her small library gave no real clues to this, nor did the nearly empty holocron that Velok found in her effects.

Abilities
Ventirri was a master of creating Force wraiths, and could use Force techniques through them. She knew the ancient Sith ability of Force Drain, which for her appeared as streams or tendrils of yellow light. She also knew Force Lightning. Velok considered her stronger and more knowledgeable than him.
