This is the legend behind the coat of arms that adorns the village bridge.
The tiles that form the coat of arms were knocked down in the storm the other day, and need to be put back in the right place.
Slide the three blue tiles into the right position, and touch them if you need to rotate.
The tiles must not overlap or stick out from the frame.
A triangle on top of a hexagon.
That is basically what the legend is saying.
So this is the design you need to have in mind.
The 'atop' in the legend is talking about the shape being in the foreground.
Place the tiles so that the gap forms a white triangle.
Use the long sides of the tiles to form the sides of the triangle.
Bear in mind that the triangle is 'reminiscent of a mountain' when ffiguring out which way up it should go.
