I can't find the caravan and the ore, could you please help me?

You should follow the stone road that leads to the village. After the peasant gives you the quest, go back to that road (there will be a cart with stones). Approach it. A message about an attack by bandits will appear. These bandits are well hidden in the bushes and are not visible before you accept the quest. To find them, follow the road "to the left, downwards." There are also small, inconspicuous stones scattered along the road, which indicate the correct path.
