You can start this quest by looting a corpse with a journal, which can be found north of Castel Ravello Vineyard signpost.
You start the quest by finding the hidden treasure located north-northwest of Castel Ravello Vineyard, Geralt will remark on something not being right. You will encounter Barghests at the location, kill them and loot the corpse to find Alistair Carnarvon's journal. After reading it, go to the marked location, you will encounter Archespores there, kill them then loot the chest in the camp to complete the quest. Inside the big hole in the ground you can find the Letter written in Elder Speech, however it's not required for anything.
- While seeking a bit of respite amidst the forests that covered the slopes of Mount Gorgon, Geralt ran into... a dead man and a pack of barghests! Once he had dealt with the spectral canines, he decided to search the pockets of the unlucky traveler. The witcher hoped he would find something that would shed some light on the deceased's last days alive.
- The dead man proved none other than a treasure hunter. That, at least, is how I would like to think of and term him (for there is no honor in speaking ill of the dead). His notes indicated that he and some others of his ilk had dug up an elven cemetery near the village of Fox Hollow. However, they had dug up one jewel too many... When the feelings of guilt and shame had grown to be too much, and the expedition's members had begun, one by one, to disappear, Alistair Carnarvon, for that was our deceased hero's name, had decided to inform a group of scholars at Castel Graupian of his find. Said scholars, he believed, would look to the ancient necropolis and extend their care over it. Alas, he never managed to reach the scholars, and the treasures he had left behind in the camp were now ownerless...
- Geralt found the camp as well as a field that had been dug up thoroughly. Strewn about it were the urns and remains of elves who had been buried there. The chest Alistair had left behind contained no burial jewels. It was, however, full of gold and highly interesting diagrams. The witcher concluded he was free to take it all, and in doing so he would not disturb the Aen Seidhe who lay there in eternal slumber.
- Read Carnarvon's journal.
- Find the treasure hidden in the treasure hunters' camp.
- In all likelihood, the title of the quest as well as the fictional treasure hunter refers to Lord Carnarvon, the discoverer of Tutankhamun's tomb, and the strange disappearances to a purported curse on the tomb.
- The Archespore fought in this quest are considerably stronger and faster than the regular variant.
- There is a slight bug with quest completion; to make sure the quest completes properly, pick up the two notes in each of the two pits before looting the chest.
