Walkthrough

 * Head to Dunnage and the Balefire Beacon. Captain Furrante will cover matters with Benweth first, then proceed to the reason he asked you to come: The Floating Hangman, a ghost ship haunting the Deadfire. You can react with Bluff 8 to boast of your encounters with it, Arcana 8 to ask to document it, and History 6 regarding the accounts of a ship flying the Darcozzi flag. The options give a Minor Positive reptuation with the Principi. Furrante will then summon Selinia, a survivor of the latest attack by the Hangman on their fleet. You can question her on the attack, then Furrante will dismiss her.
 * He will ask you to keep the affair a secret from Aeldys. You can use Perception 17 to figure out that he and Aeldys are at odds regarding the values of the Principi, use Good 1 reputation with the faction to reply in kind, or wait for him to speak. He will then direct you to the Sacred Stair in Neketaka, to find Yseyr the Berathian. If you completed Eulogy for the Dead, you already have all the knowledge you need to complete the quest right here and now. Otherwise, you need to complete The Hanging Sepulchers and find all the eulogy tablets.
 * Next, he will ask you for assistance in a delicate matter...
