Hoping for an easy victory, the imperial legions set out on a campaign against the barbarians. But they themselves turned from hunters into prey. And now barbarian hordes are trampling the lands of the Empire. They are driven by a thirst for glory, rich booty, and are united by the powerful figure of the Destroyer of Magic, whose arrival was predicted by an ancient prophecy. But the Empire of Light is still strong. Its capital seems beautiful and impregnable. And magicians remain the highest caste of imperial society, ruling the lives of mere mortals. And the magicians found an unexpected trump card against the troubles that befell the Empire. Once upon a time, two of our contemporaries ended up in this world against their own will. Now they find themselves on opposite sides of the barricades. The success of one threatens the death of the other, and therefore only one must survive. More precisely... no more than one.
