After surviving a brutal pirate attack on the open ocean, the party continues their journey north toward the remote frontier town of Hofsasel.

Their destination lies beyond the coast in a region feared by sailors and largely forgotten by history: the Sunken Archipelago. Somewhere among the drowned islands and ancient ruins rests a long-lost Temple of the Raven Queen, one of the locations hinted at within the Codex of the Fractured Loom.

To reach it, the party must first secure a vessel, gather information, and prepare for an expedition into waters where few willingly travel. What secrets lie beneath the waves? What happened to the islands that once stood there? And why does the Codex point them toward this forgotten place?
