Way to unlock: After the conversation with Dennett (the Master of Horses quest).
Quest giver: Bron (M3,4)
Bron lives on the farm, in one of the smaller houses, and he points you to three locations on the map, where you need to travel and mark them as spots, in which to put up watchtowers.
After you have marked all of the spots, (the order is up to you) [M3,4a; M3,4b; M3,4c] you unlock the Build Watchtowers Operation. Then, go to the stronghold in Haven and perform that operation, using the war table. Only after you complete it, will you be able to return to Bron and report to him on the completion of the quest.
Rewards for completing the quest:
- Experience (medium)
- 80 Influence points
- 1 Power point
