The Blackwood's Might

Reborn into a world that is both familiar and foreign Lucas Blackwood must navigate the Riverlands three hundred years before Aegon's conquest where every fourth man is king and every third wishes to be one. Will he realise his own ambitions or will his name become one of the many who failed in the past? SI, a weakness of mine. AU! with focus on war and conquest. Not a fix it fic.
