There are 16 Unknown Strange Stones all over the Countryside. You can see them clearly glowing blue at night but at daylight there are almost impossible to spot. If you collected them all (the 16. Stone isn’t found yet!) you need to carry them to this Safe Zone at the Dam and place them on the Marking in the attic. If you collected a Stone but haven’t place it and leave the Game you will need to pick it up again!
