The Old Republic Timeline
some great short narrated clips explaining the timeline of TOR in reverse, the first entry starts where TOR picks up and works backward. the latest entry deals with Malak and Revan, explaining how they relate to current events. they assume Revan was male and returned to the light side of the force, but what happened to him after KOTOR is still unknown so it's a pretty good bet there'll be some mention of him in TOR
one thing is for sure, BioWare has already fleshed out their universe more than most MMORPG's do in their entire lifespan, and TOR is still a year from release. being able to step into the game and already know the history of the last few hundred years will be a huge advantage to most RPG's
