Came back to this game after some time and I cant advance the main story at all. After your encounter with Kin'Aurea and taking young Farah to the homestead the MC say he will go to Osira to ask for help with Farah. I get to throne room she just say something and nothing happens, is there something else I need to do?? I looked some old posts here, but could'nt find any solution.
After speaking to Osira in the throne room, head to the Cathederal (where you started the game). It's in the NE part of Collusia.
In there, you'll find a Jadeite Acolyte to the left. She's next to a chest. Grab the chest (contains clothes), then head straight down to some previously hidden stairs. A scene will trigger, after which you'll be able to advance the game.
Be warned, you'll only have access to the Protagonist for a bit of time, so make sure you bring plenty of supplies as once you enter the next dungeon, you won't be able to leave until it's completed.
Also bring antidotes. No, I don't care if you think it's a waste of money. Bring them.
