This is something that has been there in my mind for a while, I was thinking about making Caine and Koji from John Wick 4.Also Lin from movie The Great Wall being descendants of Tepes family.(The Tepes family mostly marry commoners, but they do marry outside of Westeros.)
Basically one of the descendants marry a great family from Yi Ti.I am just thinking of which era they are living, whether it should be era of Robert Bartheon.
(Also has anyone seen Grave of Fireflies anime movie, it is heartbreaking and now I am having ideas of making a character Setsuko being child of Koji.)
