Star Wars: The Old Republic: Deceived

“Our time has come. For three hundred years we prepared; we grew stronger while you rested in your cradle of power. . . . Now your Republic shall fall.”
 
A Sith warrior to rival the most sinister of the Order's Dark Lords, Darth Malgus brought down the Jedi Temple on Coruscant in a brutal assault that shocked the galaxy. But if war crowned him the darkest of Sith heroes, peace will transform him into something far more heinous—something Malgus would never want to be but cannot stop becoming, any more than he can stop the rogue Jedi fast approaching. Her name is Aryn Leneer—and the lone Jedi Knight that Malgus cut down in the fierce battle for the Jedi Temple was her Master. Now she's going to find out what happened to him, even if it means breaking every rule in the book.
