I have completed one of Merlin's quest and am now able to expand my kingdom. My only problem is that I am confused on how. There is a yellow arrow that goes back and forth on the area I am able to clear but I can not get it to do anything. I have swiped, tapped, zoomed on this arrow and still nothing happens. Someone please tell me what to do in order to get past this point.
