The Revan story.

I honestly don’t think this event will take into account the lore behind Revan but more of a what-if scenario for the players that chose the dark side ending where Bastila and Revan are leading the sith army against the republic. The lore states that the light side ending to the game is canon but there exists an alternate ending which this event is likely following. It’s true that nowhere is it said that this will follow the second half of the game BUT it would make no sense if this were the time he fell during the Wars.
