Pirates and their Curses

If you have Isabella in your party, you can talk to the three statues in the dungeons. They'll reveal that they are cursed pirates from their former captain and that only another captain (Isabella) can set them free. In order to do so, you need to reconstruct the dagger of the four winds.

You can find the 4 jewels of the dagger in the various chambers of the vaults and the dagger in the main room of the vaults after deactivating the fire.

Once the dagger is compete, return to the statues where you can : 1. Allow Isabella to keep the dagger for herself, leaving the three pirates as statues forever (the dagger is restricted to Isabella). 2. Make her give up the dagger which will break the curse and free the pirates. When they're free, they will pledge themselves to Isabella. They will also give you a hand in the fight against Cahir in the cave.
