Just finished my playthrough. The right path is the "correct path". The path choice really doesn't matter as rescuing your party has no effect on the ending anyway. It would be nice also if a journal entry or something was given to lead you in the right direction because otherwise its pure luck whether you choose the correct path.
[R] Two Paths - When the PC enters the academy, Kreia tells Sion of the PCs choices to save the party or just slaughter the way to Kreia.
Is there actually a difference between which path you take? Or is it just something Kreia says?
