Belle Confronts the Masked Assailant
By following the clues left in the Tattered Journal, and using the light of Belle's Lantern to uncover memories of movements, pirates are able to find a decisive clue as to the identity of the Masked Assailant.
Given the Sea Dog insignia on the threatening letter, Belle deduces that the Glorious Sea Dog Tavern must hold the final piece of the puzzle and urges pirates to meet her there.
Upon arrival at the Glorious Sea Dog Tavern, the Masked Assailant was spotted on one of the jetties and confronted by pirates. They reveal themselves to be Amaranta and that she has created a Trident infused with the power of the Veil Stones in the Gold Hoarder eye sockets that allows the user to move effortlessly between worlds.
Belle appears on the scene as Amaranta reveals that she sent Merrick to the Sea of the Damned in order for Warsmith and Duke to interrogate him. Before Belle has a chance to stop Amaranta, she uses the power of the Staff to hop in to the Sea of the Damned.
Amaranta concluded that she will always choose the winning side, suggesting that the Brethren would be ahead of Belle and Flameheart.
