He grew up in our world - a young man who for many years did not understand why his strange father was teaching him the deadly art of a duelist. A young man who for many years did not know that one day he would have to find his way to another world... To the world that lies, invisible and unknown, next to ours... To the world hitherto ruled by the Great Houses of Fire, Stone, Sky and Water... To the world , where impregnable fortress cities stand, carved into the thickness of mountain ranges, ancient gods roam hitherto, wolf-men seek prey, and battle crows fly. In a world where disputes between the Dukes of Houses are still resolved in duels. To a world where mastery of the blade is still valued above all else.
