Fill each of the empty circles above with a unique letter. Each of the three letter groups represents the order you would encounter these letters going around one of the heptagons clockwise. For example, ITM means going clockwise around one of the heptagons, after you hit I, you will hit T before you hit M. Once all of the letters are filled, the dotted spiral will spell out one final word. What is that word?
