Civitas Vadanis is in trouble. The Mezentines have declared war; and the Mezentines are very focused on their goals when it comes to killing. Duke Valens, of Civitas Vadanis, has a dilemma. He knows that his city cannot withstand the invading army; yet its walls are his only defence against the Mezentines. Perhaps the only way to save his people is to flee, but that will not be easy either. Ziani Vaatzes, an engineer exiled by the Mezentines for his abominable creations, has already proven that he can defend a city. But Ziani Vaatzes has his own concerns, and the fate of Civitas Vadanis may not be one of them.
