Here is a timeline i made of the starcraft universe a long time ago. It doesn't go into the episodes because we all know what happened during that time. Im a little hazy on the guild wars and when the exiles exactly arrived at the k-sector. In the game it says that "in the decade since the end of the guild wars the confederacy stood unchallenged in its supremacy over colonial space", so this leads me to believe the guild wars ended a decade before the events of Episode I however this isn't consistent with the info in the manual. Also, im not sure when the exiles really arrived in the Australia of space, since all it says is that they left sometime during the 40 years of terran expansion, just not exactly when. However im inclined to believe that it was close to the beginning because it says in the manual that the protoss watched over the burgeoning race of humanity for 2 centuries, and if they left at the beginning that would be closer to two centuries. Also, keep in mind that Metzen is setting down a definite timeline for starcraft 2 as well. So we should see some clarification when sc2 comes out. ;D
