I have no idea where the Winged Hussar is from (some scenario after Gods and Kings, I presume), but no, I am not the Winged Hussar.You really haven't been paying attention to BNW huh?
Marathoner's turn right?
Nope. But good guess
That clue is a little bit too ambiguous. We could gather all the monarchy leaderheads in the game and just take a stab, hoping to pick the right one. There's also Leif Ericson and possibly other Great People.
My official guess is the Khans, Kublai to be specific.
You clue is to vague, due to the fact that dynasties have existed.
