Mage Questor Grimm Afelnor and his companions find themselves in Haven, a steel fortress in the forbidding Shest Mountains, as the unwilling guests of Armitage, the reborn avatar of a long-dead Technologist, who holds ancient techniques of mental control. After being forced to fight a magical duel, Grimm and his nemesis, Questor Xylox, break free and battle the hellish array of Technological devices at Armitage's command. However, even defeating Armitage and his minions is not the end: a traitor lurks within Haven's ranks, an envious man with his own megalomaniacal agenda... Grimm and his companions then face a gruelling trek through a scorching desert before taking on a mighty army headed by the feared but charismatic General Q. Opposed by hordes of troops with metal weapons, several fanatically loyal if enslaved Guild Mages, and an equally dedicated Technologist, can even two potent Weapons of the Guild prevail?
