Sevean

Hey guys, I'm sorry if this question has been addressed before, but I wasnt able to find an answer in the forums. How is Sin's lore presented throughout the game? I know that there is no single player campaign... instead its more of a sandbox experience. Does Stardock delve into the backstory some throughout the individual scenarios, or is it just the intro cut scene that Ive heard about? I'm interested in the whole Vasari exodus... shame there's no campaign :( <
