At the start of Act 2 in Path of Exile 2, you embark on the Ardura Caravan. The massive town on wheels is being pulled by slaves through the Vistiri Desert. However, it’s being stopped by a vicious sandstorm, and you need to find a way to get through it as a part of the Trail of Corruption quest.
As you meet more characters on the Ardura Caravan, you’ll be directed to travel to new regions and find a way to stop the sandstorm. Unfortunately, getting off the caravan and traveling to new places isn’t as simple as it sounds.
Leaving the Ardura Caravan in Path of Exile 2
After meeting with enough people onboard the Ardura Caravan, the Trail of Corruption will update with the objective: “Travel to areas of reported corruption.” Of course, that’s a fairly vague objective, as the caravan is moving the entire time you’re on it and you haven’t visited any new locations to fast-travel to.
