Affably Evil by Sarah1281. It's an alternate take on her other story, So Not My Problem, where Malak is the one who gets ambushed by the Jedi, rather than Revan. It's only three chapters, so far, but it looks great. She also has a bunch of great Supernatural fics, if you like that series. Also, So Not My Problem has a sequel, The Jedi Kind of Had it Coming, which follows the plot of Star Wars: Knights of the Old Republic II - The Sith Lords, with Revan along for the ride.
