Quite spoilerish, but you asked:
Start outside the gate to the druid grove. Face away from it. Go right (towards Blighted Village). Shortly down the road, on the left, are some terraces. You have to jump to get to the first one, but after that, you can climb. Keep going up. The very top has a Harper outpost that has some nice views and two important items. The first is on the skeleton - an amulet with Guidance. When you get close to some rocks near the edge of the top terrace, you will get a Perception roll to help you find a hidden item. Get it (takes a successful skill roll, which you can use your new amulet on) and experiment.
Also, on the other side of the road from the Harper outpost is a hidden doorway (Perception roll) which leads to a small area with some useful stuff.
