In a universe where races struggle between war and peace, one race sits comfortably on top. Thus one man is commissioned as the Supreme Empress' faithful assistant. Xavier does Her Majesty's bidding as Her Master Assassin. Killing is his life and no task is too overwhelming. Except those days when he is ordered to follow the whims of Her High Princes to keep his cover. When not out to insure the supremacy of his race how is a Master Assassin supposed to relieve boredom? Sometimes being an assassin requires being a master of disguise.
