As legendary engineer Athelend finishes his latest project, he receives a letter again requesting his services. But this request is outside his area of expertise, and he is unsure if he can pull it off. On the other side lies Himmuradii, a celebrated general on his way to earn more glory for his king. But standing in his way lies Athelend's new creation, newly finished and highly formidable. Himmuradii must do all he can in order to save both his men and himself from the obstacle in front of him. But It is not the fortress that Himmuradii should fear the most, it is those beside him and behind him that are his greatest threats.
