As far as I can tell, there isn't a compact guide for this quest, so I'm making one.
The Blackbeards Secret Note drops from pirates on the Beach at White Sand Harbor, after activating it, you need to head to Haldek Farm, and talk to an NPC who who tell you to get 3 Dieties Parish from Bloody Inquisotors at White Sand Harbor.
The Bloody Inquisitors are a pain. Bring along a 4x+ fighter/archer, and preferably a priest with dispel 3 (The pirate captains use the invader debuff). Dont even try to solo them if you're under 35, unless you have great gear and are willing to risk a death. The Bloody Inquisitors also heal and use a damage/slow AOE. The Dieties Parish drop 1/3-1/4 of the time, so expect to be there a while.
The reward changes based on which responces you give the NPC's. Head back to Haldek. Poema will give you an item to deliver to Apulune. Bring it there and Talk to Lana Fairwind. I have NOT tested all of these, I've compiled this from various posts.
