Enter the [Lost Sector] Lost Sectors in Trostland in the EDZ, and reclaim the fragments from the caches guarded by Fallen Captains.
The Lost Sectors are hidden in the area surrounding the church… and maybe even within. Look for the [Lost Sector] symbol in the world to find them.
"Is it stealing if we're just taking back what they stole in the first place? Turnabout is fair play." —Devrim Kay
Devrim Kay, a scout in the EDZ, believes the hidden pieces of Cayde's treasure map have been stolen by Fallen scavengers. If you can reclaim them, they will lead you to the lost weapon frame.
