The wicked witch noticed that the power of light was growing at the ruins of Gil-Garoth as the towers started going up, and decided to try and stop the magic schools from harvesting the magic stones. THE DARK TOWER is a expansion from "The Towers of Arkhanos" which adds 3 new modes of play: 1 The SOLO MODE, in which you try and build the towers before the witch builds hers and sends her goblins to get in your way; 2 The Witch's game, a new set of rules to play a game of "Towers of Arkhanos" in a totally different and fun way; 3 And the grand master special ability cards. The Towers of Arkhanos is a fast dice drafting, tower building family game of pure magic and fun. —description from the back of the box
