The second limited-time Adventure in Sea of Thieves has arrived, continuing the ominous narrative of Flameheart’s return to the seas. This chapter builds directly upon the events established in the Shrouded Islands debut, advancing the overarching storyline while offering substantial gameplay rewards.

Forts of the Forgotten represents Rare’s ongoing commitment to evolving narrative content within their pirate sandbox environment. Available exclusively between March 24 and April 7, this Adventure provides both narrative depth and practical incentives, including control of valuable Sea Fort locations and time-limited cosmetic items that will become unavailable once the event concludes. Successfully navigating this content requires strategic planning and efficient execution.

Most crews will require approximately two hours to complete all objectives, though completion times may vary significantly based on server population and fort availability. With only six Sea Forts distributed across the entire map and high player participation during the initial release period, you might encounter situations where you need to wait for fortresses to reset before engaging their phantom defenders.

Your journey begins with Larinna, who remains stationed outside any tavern where you spawn into the game. Initiate conversation with her and select the option to begin the new Adventure. She will direct you toward Golden Sands Outpost, which serves as Belle’s current operational headquarters within the ongoing narrative.

Navigate carefully toward Golden Sands, remaining vigilant of the persistent green fog that continues to shroud the area. This environmental hazard significantly reduces visibility and conceals dangerous rock formations that can damage your vessel if struck. Secure your ship properly at the dock and locate Belle at her campsite situated just beyond the previously vibrant tavern building.

Pay close attention to Belle's specific instructions.

Belle will share crucial background information about the current supernatural threats, establishing appropriate atmosphere for the ghostly tasks ahead. She provides explicit instructions detailing three primary objectives that must be accomplished to complete the Adventure successfully.

The mission parameters clearly specify three non-negotiable tasks: first, you must defeat a single Jailor; second, complete one Sea Fort in each of the game’s original three geographical regions; and third, transport at least one Enchantment Vessel back to Belle at Golden Sands Outpost.

For players unfamiliar with Sea Fort mechanics, these locations function similarly to Skeleton Forts but feature phantom enemies rather than skeletal warriors and typically require only about one-third of the time investment compared to their bony counterparts.

The Jailor has the sought-after Prison Cell Key you've been waiting weeks to find.

Every Sea Fort culminates with a confrontation against a Fortress Captain, who serves as the location’s boss encounter. Upon defeat, this spectral commander drops a Treasury Key. While the treasury typically contains loot valued over 10,000 gold, accessing this wealth represents an optional objective rather than a requirement for Adventure completion—though certainly worth collecting if time permits.

The critical requirement that demands particular attention involves completing at least one Sea Fort across all three primary regions where these structures appear: The Wilds, The Ancient Isles, and The Shores of Plenty. Each region contains exactly two Sea Fort options, providing these selection possibilities:

  • The Wilds: Mercy’s End Fortress or Traitor’s Fate Fortress
  • Successfully assaulting Sea Forts requires understanding both combat mechanics and strategic approaches. Phantom enemies exhibit different behavioral patterns compared to skeletons, often employing teleportation abilities and area-of-effect attacks that require adapted defensive strategies.

    When approaching Sea Forts, consider parking your vessel on the side opposite other player ships to minimize confrontation risks. Utilize the fort’s verticality to gain tactical advantages, and remember that phantom musketmen typically spawn on upper levels while sword-wielding phantoms dominate ground floors.

    The regional distribution of Sea Forts provides strategic options for planning your route. In The Wilds, choose between Mercy’s End Fortress or Traitor’s Fate Fortress. The Ancient Isles offers two additional locations, while The Shores of Plenty contains the final pair needed for completion.

    Efficient completion requires understanding several advanced strategies. Begin with the fort furthest from Golden Sands to minimize backtracking, and consider completing multiple forts in the same region if they become available to reduce travel time between objectives.

    A common mistake involves misunderstanding the regional requirement—you must complete one fort in EACH of the three regions, not simply three forts total. Additionally, many players overlook the importance of the Enchantment Vessel, which must be physically transported back to Belle rather than simply collected.

    Player competition represents the most significant variable in completion time. During peak hours, you may need to server hop to find less contested forts, or coordinate with other crews to minimize conflict. The Jailor encounter typically occurs at specific locations that may already have player activity, requiring diplomatic approaches or tactical patience.

    Navigation through the persistent fog around Golden Sands demands careful piloting. Reduce sail area when approaching the outpost to maintain maneuverability, and assign a crew member to the crow’s nest for better visibility of hidden obstacles.

    For optimal efficiency, we recommend consulting our Complete Guide to Battlefield 6 for additional strategic insights that can be applied to naval combat situations in Sea of Thieves.
