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.
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!
