Duncan Gelahn, the Mind Executioner, is a man determined to destroy Gathandria and the countries around that city. Born under the sign of the Lone Man, he has been held as a solitary prisoner by the Elders for so long that he is determined to exact his revenge. At all costs.
This revenge involves manipulating both Simon and Ralph to ensure that Gathandria comes under his own power and that those who have thwarted him are executed. At the same time, Duncan's possession of the mysterious mind-cane gives him a distinctive edge. He is a man of many secrets who can never be trusted. But will his thirst for vengeance be enough to give him success?
