The Collection of Dragons and Snakes is a World Quest that tells the story of Ema, who, on the last day of Byakuyakoku, is fussing over some library books that delinquent borrowers have yet to return. To unlock this World Quest, you must first complete The Subterranean Trials of Drake and Serpent and set your daylight settings toEvernight.

Start by heading back to the library in The Narrows. Its exact location is circled in the image below. Once you’re inside, go up to the second floor to meet the afterimage of Ema, the librarian-in-question.
