It is a time of vengeance in a galaxy far, far away. Darth Malgus steps out of the shadows to lead the Sith in striking a fatal blow to the heart of the Jedi Order. Crimson blades rain death and pain upon the Republic as Coruscant falls. But even in triumph, Darth Malgus discovers betrayal by his own bretheren, a quest for peace with the Republic that will only corrode their hard-won power. As the dark lord plots against the Sith leading their own kind to ruin, vengeance hunts him in turn. Her name is Aryn Leneer -- a Jedi with nothing left to lose on a quest to avenge her slain master.
