In FOTJ it's stated several times that Jacen Solo managed to avert a dark future for the galaxy by becoming a Sith Lord. I'm wondering what exactly that dark future was. According to Abyss and Apocalypse, Jacen saw a Dark Man on a golden throne, ruling the galaxy. We see in Apocalypse that Jacen's Dark Man was in fact Darth Krayt, and that Jacen did what he did because he saw Allana standing next to the Dark Man. That was why he turned to the Dark Side, to save his daughter. He seems to have succeeded, as Darth Krayt hides in the shadows for over a century before finally emerging and taking over the galaxy. But what exactly was that future that would have come, had Jacen not turned. Would Darth Krayt have emerged from hiding early? Would the One Sith have taken advantage of the Corellian Uprising and and tried to seize control of the galaxy?
