Enter Valley Pass

Immediately after Main Mission Westward into the Vale, head straight forward across the bridge that you just lowered. Keep following the road, activate the fast travel point along the way, and at the end you will get a cutscene. A red mist called the “denstack” is blocking the way.

Look around for another path

Turn right to find destructible wooden crates, hit them to clear the path.

Progress down the trail / Keep advancing

Keep following the path behind the crates. You will run into a group of Landbreakers.

Defeat the Landbreakers

Beat them up!

Catch up to the fleeing person / Defeat the Landbreakers

One of the people who was held by the Landbreakers is running away. Follow him. There is another enemy group along the way, which contains a stronger Chief. Afterward, the guy who ran away (Mr. Karja) requests your help in saving his sister.

Follow Karja to the shelter

Simply walk after Karja, who has an objective marker on him. The shelter is only a few steps away.

Give Ginny some medical attention

After you meet the other settlers in the shelter, interact with Ginny on the floor. You will automatically give her some medicine and she’ll feel better right away. You also learn that Originium Mining is causing her health issues.
