Droktagar did not begin with walls.
He understood, after two days of walking the highland settlement and observing how the clan moved through it, that walls were the wrong first project. Walls were what builders built when they were proud of what they were building. They announced: this is permanent, this is ours, this will be here when we are gone.
A people who had spent generations moving did not start by announcing permanence. They started by accepting that a specific problem was easier to solve permanently than to solve daily.
The problem Droktagar chose was water.
