Oh gosh an Agents of S.H.I.E.L.D. AU?! Sign me up!!! Now I'm going to be busy casting the characters in my head all day...
Though I feel like Leliana = Agent May is pretty much a given.... 
Cullen and Alistair just had a conversation with Skye/Daisy and a slightly still shaken up Simmonds. I think Alistair has a thing for Gemma and Daisy not so thrilled with Cullen ( kind of reminds her of pre evil ward).
Ugh...
And why I actually popped on today, since I'm not lurking like yesterday (honest), is I ran across an old favorite book series: Daughter of the Empire by Raymond Feist and Janny Wurtz. While not exactly Cullen, it does have a relation to DA in that the plot of the series revolves around this world's version of the Grand Game.
I know TME gets into it, but this gives a great example of a noble house's involvement in the Game on an almost daily basis, and what it feels like to have even the most common tasks judged by the standard.
That and it's a fun read. Plus Kevin of Zun rocks.
