I love that idea of a Game of Thrones cross over. I have been thinking about writing Aragorn's grandmother as a bit like Lady Olenna Redwyne-Tyrell, Loras' grandma, the Queen of Thorns. Problem with that is the research into the Northern Numenoreans would be a major pain in the ass (and it always kind of depresses me) and would take me forever. Not exactly what I want as a one-off challenge fic, but that would give me a Bingo if her number was called on the Women of Arda card. I think I did miss one prompt on the Sons of Feanor card. How is that even possible???
