Since this was a success last time, I figured I'd try it.
Varys, you are dearly wanted over at maester. Tyrion is doing his best to hold everything together as things progress but he would dearly like your counsel and your assistance. Plus, as an added bonus, you get to read Littlefinger's execution thread.
In general, we also need a Bran Stark. He's still beyond the Wall in our current storyline but we just got a Meera, who is dearly looking for the guy she has to drag back to the Wall/Winterfell. Please, come to us, tell us how beautiful we looked as we were going through major trauma.
For wylla and wynafryd, we would love a Wyman and/or Wylis Manderly to deal with their daughters. Wylla's been getting into some trouble, so having her father/grandfather around would be A+.
We also have a wanted list if you need more ideas!
