Star War's the Old Republic: Darth Revan's apprentice.

A storm is coming and there is no escape.

Ja-ni: hero, traitor, conquer, villain, savior. A Sith Lord who left Korriban to defeat the Jedi and returned a disciple of the dark side, bent on destroying the Republic. The Sith Lord's gave Ja-ni her life back, but the price of redemption was high. Her memories have been erased. All that's left are nightmares and deep abiding fear.

What exactly happened beyond the Outer Rim? Ja-ni can't quite remember, or entirely forget. Somehow she stumbled across a terrible secret that threatens the very existence of the Sith. With no idea of what it is, or how to stop it. Ja-ni may very well fail, but she's never faced a more powerful and diabolic enemy. But only death can keep her from training.
