Treasure Hunt: Temerian Valuables is a Hidden Treasure Side Quest in White Orchard. This place is located on the stone bridge North of the town of White Orchard, bridging the path to the Nilfgaardian Outpost with the road to the large mill on the other side of the river.

The bridge itself may sometimes harbor one or two Drowners on either side, and the bridge also has suspicious blood stains on it. By diving into the river below you'll find the source - a carriage, passengers and all, lie at the bottom. The one chest in particular is locked, but a corpse on the shore holds the Temerian Lily Key. Opening the chest provides a note that starts the quest and provides more clues - a convoy was to be sent towards the mill, but something must have happened.

Using your Witcher Senses, head past the old mill and into the large abandoned hut. On the right is a secret basement covered with a few loose boards that you can drop into. Head down into the cave and open the door to find the treasure - several chests full of randomized (but good) loot. The final chest can only be opened with the key, so if you happen upon this place by accident, or through the other Hidden Treasure quest, you'll need the key to get everything in here.

• Note: because The Mill is also a location for another quest (The Beast of White Orchard), the enemies, including the one who has the key to the chest in the basement, will not spawn until you have completed the other quest
• Note: Completing this quest will disable the other quest: Treasure Hunt: Deserter Gold
