Game of Thrones: Raven's Oath

The fate of a time traveler has never been to be infused with dragon flames, nor to have noble blood. The game of thrones is still going on, but the rules of the game are being quietly rewritten by a variable that shouldn't exist. When the cold winter of the White Walkers descends on the Great Wall, and when the shadow of the true dragon crossing the sea envelopes the Seven Kingdoms, what Genos has to face is no longer the conspiracy of a certain prince or a certain wedding - but the end of the world itself. The crow will not forget the oath, and he is becoming the oath itself. The sobriety and calculation of a working man, the brutal growth of a system, a Westeros counterattack about power, love and survival.
