Dragon Age: The Veilguard

After completing the main quest, “The Siege of Weisshaupt,” in chapter 8, you’ll find yourself back at the Lighthouse ready to crack on with the 9th chapter. However, before you do, head over to the exclamation point at the Lighthouse and speak to the Caretaker.

The Caretaker will tell you about the notorious Black Emporium, one that has appeared in Dragon Age games before. This will start the side quest, “The Black Emporium,” which will take you to the backalleys of Dock Town.

Follow the directions and quest markers, and as soon as you step foot inside Xenon the Antiquarian’s Black Emporium, the ‘A Most Esteemed Purveyor’ achievement will unlock.
