Step 1: Start the Dark Brethren Tall Tale
As soon as you start the Tall Tale, The Castaway will start talking to you and your crew. She explains that Davy Jones is extremely upset that his plans for Jack have been thwarted and that the Sea Queen has been vanquished.
The Castaway will reveal Captain Jack Sparrow who has secretly been listening. She then reveals herself to be Calypso!
She came to the Sea of Thieves to protect the waters from Davy Jones. The pirates of the Sea of Thieves threaten Davy Jones and he wants to put an end to this domain for which he has no control over.
As he has had to put up a good fight, he has summoned his own version of the Brethren Court.
With Jack at our side, we need to break into the Coral Fortress, where he will be holding his court.
Step 2: Sail to the Coral Fortress
On the last page in your Tall Tale book you will find a map of where you need to sail to.
The Coral Fortress is located above I1 and J1, just a bit into the red sea, extremely North on the map.
As you approach you will be greeted with large waves, cold rain and harsh winds.
Step 3: Enter the Coral Fortress
Sail up to the South side of the fortress and you should find a large entrance highlighted with blue coral.
Head inside and you’ll come to a stone door with two large mermaid statues on either side and Captain Jack Sparrow. Jack will open the door with a locket from Tia that was left on the Black Pearl ages ago.
The lock plays music that is near and dear to Davy Jones. Jack will hold the locket up to the door and after it plays its tune the stone door will open.
Head inside and you will swim through an underwater tunnel. You’ll come to a dead end but Jack will help you up and remove the blocking stone.
Step 4: Traveling through the Coral Fortress
In this small cavern, stand on the geyser to be push up to a ledge. Use the pulley to bring a wooden beam closer to you to jump on. Jump across and continue to make your way up the path.
You’ll find Jack waiting for you just before he slips backwards down a slide. Follow him for the ride!
Step 5: The Chamber of Sorrow
The water slide will spit you out into a giant chamber with the Flying Dutchman. You’ll want to board the ship. Unlike galleons, you’ll find the ladder up near the front of the ship.
Head down into the hull to the map table and remove the dagger.
Doing this will awaken the ship and the door to the organ room will open.
Head inside to find Jack holding Sheet Music.
Pick up the Sheet Music and use the organ.
Step 5: Solve the Organ Puzzle
To solve the organ puzzle you will want to take note of which keys are more worn than the others. You’ll notice a set of keys to the left that are more worn. The leftmost white key has a big scratch on it that looks like the number 1. This is your starting position, key one. The last key in the grouping is key eight.
If you look at the sheet music, you will see the keys you need to play and in which order. The number on each key is the order.
You can move around the piano keys by pressing left, right, up and down. You play the key by pressing your jump button.
Following the sheet music: play key one, play key two, play key three, play key four, play key five, play key eight, play the black key between key five and six, play key five.
Playing the keys in the proper order will light all the candles and start a large battle!
Step 6: Defend the Flying Dutchman
After completing the organ puzzle, waves of enemies will fire down upon you on the ship. You have to wait for the song to complete and the giant door behind the Flying Dutchman to open. Each wave you complete, a giant siren statue will emit a red glow. Once all the statues are glowing and the waves are over, the door behind the Flying Dutchman will open.
Step 7: Travel Through the Fortress
Swim through the area just opened up and you encounter a few sirens. Dispatch of them and move forward to a large room with water pouring down.
Dive below and you’ll find three pieces of shipwreck tied down by weak rope. Break all six pieces of rope and the platforms will rise.
Use the newly created platforms to jump across to a platform with a ladder on it. Climb up the ladder and use the pulley to lower a wooden structure nearby.
Head to that wooden structure and Captain Jack Sparrow will appear. You are currently blocked from progressing but Jack will help you out. He will open up the rock door and you can continue up.
Once up top, you will meet Jack again but your progress will be blocked by a wooden door this time. Jack will give you a Siren Heart that will hopefully help you get past these obstacles.
Put the heart in the one of two statues that is missing one. Match up the painting in the room with the two statues so that both siren statues have their arms raised high. Damage the siren statue with the conch and the wooden door will lift for you to proceed.
The next large cavern has three siren statues you need to match with their paintings. Ignore the pulley for now. You will immediately see one siren statue in front of you as you walk in. Its corresponding painting is just to the left of it. Make this siren statue’s arm low.
The next siren statue can be found if you walk to the end of the handing shipwreck. Look to your left and you will see the painting and the siren statue above it to the left. You’ll need to shoot it to raise its arm to middle. You can find an armory next to the first siren statue.
The third statue can be found if you look to the right when standing at the end of the shipwreck, opposite the one you just did. It’s high up and you’ll need to shoot this statue until its arm is high.
Once you have all the positions correct, shoot the siren statue with the conch. You can see this statue if you are standing at the end of the hanging shipwreck.
Once you have complete the puzzle, the waterfall in front of the shipwreck will go away. Walk back to the first siren statue near the ammo and armory to find a pulley. Use that pulley to lift the shipwreck. Run up the shipwreck and jump across.
Continue to make your way up and cross several masts over large drops.
You’ll come to another siren statue puzzle. Both arms should be high. You’ll find the conch siren statue you need to damage at the other side of the mast you just crossed. Damage the statue and the door will lift.
Fall down into the next room and prepare for battle!
