I’m not sure what “the sunken requil” refers to, but the closest match I found is Sunken Reliquary from Fisch, and there’s a guide that says the area is reached as part of the Tidefall update content and progression through that zone starts with the area itself rather than a separate hidden entrance.

If you meant something else, here are the most likely interpretations:

  • Sunken Reliquary in Fisch: The guide says it’s a complex zone tied to quests, bestiary progress, rod upgrades, and mining essence, and it includes a “Finding the Area” section.
  • Sunken Pearl in Sea of Thieves: That is a different “sunken” location, but it’s a Tall Tale rather than a regular zone, and it is started from the Castaway’s Camp on any Outpost.

What the guide says

The Fisch guide specifically frames the Sunken Reliquary as a place you enter as part of the Tidefall progression, with nearby objectives like the Fallen Flying Gurnard quest, Infusion Altar, relic crab cages, and Omnithal hunting once you’re inside.

Best next step

If you want the exact route, tell me the game name or paste the quest text, and I can narrow it down to the correct entrance, NPC, or trigger.
