This is a simple quest which forms part of the main quest The Descent. All you need to do is establish three Inquisition camps within the Deep Road and the Abyss. These can be found in the following locations:
The first camp is impossible to miss as you progress through The Descent main quest, and is first encountered at the Storm Coast Fissure.
The second camp can be found in the Ruins of Heidrun Thaig. In particular, you will find it in the region before you approach the lift to the Forgotten Caverns.
The third camp can be found within a cave in the Bastion of the Pure. More specifically, it is in the region immediately before you enter The Wellspring.
Once all three camps are established, the quest will complete.
