There's an Undiscovered Location in the marsh west of the Pontar. Head there to find a corpse holding a mysterious key and a letter. Read the letter to create a search area nearby. Head there and use your Witcher Sense - mind the Nekkers! - to find a chest underneath a collapsed wooden structure. Use the key you found to loot the treasure inside.
Prerequisite: None | Suggested Level: 18
Southeast of the Devil's Pit marker is an Undiscovered Location, a Hidden Treasure identified by an overturned cart. Examine the bodies there to collect a small key and a letter. Then, simply read the letter you found. That's it.
Hidden from the World
Prerequisite: None | Suggested Level: 7
Head east from the Marauder's Bridge marker to find a Bandit Camp marked as an Undiscovered Location. The loot here is a letter - read it to learn of another treasure. Head to your new marker to the south. This will lead you to another loot chest atop a hill. Raid it to finish the quest.
