So, in Hasongo there is a bunch of rubble that as far as I know cannot be destroyed or traversed by normal means and on one side of it there is a big group of Nagas. I managed to go around them and get to the rubble from the other side, but I aggroed them and the first thing Eder does is charge through the rubble into the huge group of Nagas, essentaily separating my party with no way(that I am aware of) of reuniting, since I would have to change scene and for that, the party has to be together. Pic related.
My only option at this point is to load an earlier save file.
