Merfolk's Lullaby

A new building appears on all Outposts, with The Castaway taking up residence in them.

The Castaway implores pirates to seek out someone lost in the Sea of the Damned, beginning a series of events that changes the course of the Sea of Thieves forever.

As part of Davy Jones' plans and his alliance with the Siren Queen, Sirens begin attacking Pirates who spend too much time in open waters.

However above the waves the Siren Queens personal constructs, the Ocean Crawlers, attack pirates using their powerful poison, electrifying eel whips, and crushing claws.

Pirates were sent to the Sea of the Damned to find a specific individual, winding up at Dead Man's Grotto and then Sailor's Grave. Here they came across the Cursed Captain and helped him to make right by his crew. In return, he helped pirates to sneak aboard the Ferry of the Damned.

Sneaking aboard the Ferry of the Damned, pirates placed the foreign Flame of Fate within the Well of Fates, causing it to implode and create an opening to the lower decks of the Ferry.

Here they meet with Captain Jack Sparrow and release him from the hold.

Shortly after, the Flying Dutchman attacks. In the midst of the struggle Jack loses the Greatest Pirate Treasure to an Ocean Crawler and then falls overboard into the Sea of the Damned.

The Castaway sends pirates to the sunken Black Pearl to retrieve an item that will help them to find the whereabouts of Captain Jack Sparrow.

Pirates find the ship chained to the bottom of the sea and retrieve Jack's Compass from the captain's quarters of the wreck.

The search for the sunken Black Pearl leads pirates to the Sunken Kingdom, a domain below the waves belonging to the Sirens. Here pirates are lured by a mysterious voice through the Siren Spire and Siren Citadel, eventually leading to a confrontation with the Siren Queen.

With the Siren Queen's defeat, the pirates leave the Citadel, freeing Gibbs, Anamaria, and Scrum from Cursed Mermaid Statues on their way out.

Opening up another Tunnel of the Damned, The Castaway sends pirates to locate Jack in the Sea of the Damned. Jack's compass leads pirates to a journey through memories and stories of his life.

Once Jack rescued and arrived at the Tavern of the Damned, a rousing speech from Sir Arthur Pendragon convinced Jack to return to the land of the living and fix the problem he started.

With Jack Sparrow in tow, The Castaway directed pirates to the Coral Fortress, the bastion of Davy Jones, in order to get back the Greatest Pirate Treasure.

As pirates and Jack make their way through the Coral Fortress, the Dark Brethren convened in the heart of the fortress, where they discussed their plans for a ritual to merge the Sea of Thieves with the Sea of the Damned.

To save the pirate's life, the fight had to be brought to Davy Jones and the Dark Brethren. Climbing up the Coral Spire, Calypso with the aid of pirates destroyed the Heart of Davy Jones, weakening him considerably. A final confrontation happened between the Flying Dutchman and the Captains of the Damned.

Davy Jones subsequently defeated and his plans put to a stop, the Ferryman locked him away in the hold of the Ferry of the Damned.

The Ferryman appeared aboard the restored Black Pearl to return the Greatest Pirate Treasure to Jack Sparrow and congratulated the group of pirates on saving the Sea of Thieves from disaster. He granted Wild Rose and George a second chance at life, Eli Slate and Sir Arthur Pendragon turned down the offer.

Wild Rose and George opted to stay with Jack Sparrow as part of his crew. Jack used the power of the Greatest Pirate Treasure to open a new portal to a new horizon, which he and the Black Pearl sailed through.
