The 12 pieces are found in the Western Approach in the following locations. The pieces are numbered to match the reference image:

  1. In Sand Rock Mine near the red lyrium vein
  2. Outside of Still Ruins
  3. In Echo Back Fort, past Coracavus inside the area between the Gate of Andoral and the Gates of Toth
  4. In the cave in the Western Approach, south of Nazaire's Pass Camp. The cave becomes accessible once the Abyssal High Dragon is killed. The rock blocking the entrance can also be broken by a warrior using Grappling Chain. Moving around the statue in the cave in the left direction brings you first to Piece #4
  5. Same location as #4. Moving around the statue in the cave in the right direction brings you first to Piece #5
  6. In the cave at the end of On the Chantry Trail
  7. In the astrarium cave
  8. Under Griffon Wing Keep in the Old Well, near the keep's landmark.
  9. In The Thing in the Dark Cave, in Death Drink Springs, requires the war table operation Crossing the Sulphur Pits to be completed
  10. Beneath the final platform after climbing down the Hidden Stairway landmark near Craggy Ridge Camp
  11. In the Lost Wash Creek Cave (called Oasis Cave on the map) near Lost Idol landmark
  12. North-east of the Gates of Andoral, past Coracavus on a table in a Venatori camp between the gates and Echo Back Canyon Camp
