Description: A tall man in 30s or 40s with a powerful physique. Theyre looking for someone with 'mixed ethnicity' for the role. Who It Could Be: The mixed ethnicity suggest this will be a character from Essos rather than the Seven Kingdoms, and the chances are this will be a part of Daenerys storyline. Most likely it will be a Dothraki warrior, quite possibly Khal Jhaqo. At the end of A Dance With Dragons, Dany is found by his khalasar, so itd make sense if the early casting call was for their leader. We dont know what will happen in the next book, but it could be that she either makes a pact with him, or (more likely, given her history with him) has Drogon kill him, but either way she may have a new Dothraki army behind her next season. It could instead be Strong Belwas. Please be Strong Belwas. (It isn't going to be Strong Belwas.)
