The Song of Builders

During a fight with a dragon, Head Auror Harry Potter and a few others are transported to another world. Years later, Westeros and Essos are a little smarter and a little more honorable. The players of the Game of Thrones become pawns when the Builders raise their fist and strike. This is the Song of Builders, a song millennia in the making. Story starts at the end of "Baelor."
