This mystery can be found in the western part of Vangrinn, northwest of the Hodda Shelter. As you approach the area you’ll hear a dwarf named Jordri in some distress. This dwarf isn’t beset by Jotnar or Muspels, though. Instead, he has a problem with what he calls his sacred duty: to hide his most beloved treasures behind a waterfall. Apparently, this has been done for generations in his family. Why? Because waterfalls with nothing behind them are waterfails…
In any case, Jordri needs help to get his treasures behind a nearby waterfall. You should offer to help.
Where to Place the Treasure Chest Behind the Waterfall
The waterfall that you need to carry the treasure chest to isn’t too far away, but you’ll need to climb over some rocks and other obstacles to reach it. You can easily fall from these if you’re not careful, and the treasure chest may be lost to the waters below.
The path to the correct cave behind the waterfall is fairly intuitive to find, especially if you follow the tree trunks and white rock markings which provide clues to the route. However, if you’re having trouble locating the cave you can see the gif below, which shows exactly where you need to go.
Once you’ve placed the treasure chest on the ground in the cave, be sure to pick up one of the white flowers to prove that you’ve been there when you return to Jordri.
