Wild Arms - Part 16: Sacred Shrine Dungeon

In the last video, I looted this place, which saves us some time now. The villagers try to take refuge in the shrine only for the defenses to be sabotaged, leaving it overrun. We need to travel the entire thing and talk to people to try to figure out what happened. After speaking to the last person, a prompt will appear where you have to figure out there is a traitor (the mini-boss is an indicator of this...) and then you can go all the way in.
