Follow the road south from the bulwark and look behind the destroyed home, next to the cliff face, for the first defense console. Return to the bulwark and head straight west along the road into town. There are at least five additional defense consoles circled around the town center here. You can find them by following the snaking power lines along the ground.
Once all five of the defense consoles have been activated continue west through the city to the next encampment. Turn the quest in to Koke Tegus at Koke's Hold.
