Well I decided that the Wall should be made, the coolest thing in all the series. As far as I am in the books, the wall was built by Brandon the Builder. So the first thing that comes to my mind is that it should be able to produce rogues somehow, and to have some draw back power, to save rogues from field. So i came up with this:
Then i decided that I should make a Castle Black. The most populated building around the wall. So basic concept is something like this, it is a land, able to produce white mana, since Night Watch's Warriors are W/B. And it is able to help cast rogues, since they basically live in Castle Black so that should be ok.
And then the coolest ranger, and the most skilled i'd say. Benjen Stark, he is legendary, on the card and in the show. So he puts lives of his teammates first and i think that is the Exalted part, and everyone is stronger being alone while sneaking right? And his ability is just a motivate ability, since he invited Jon. And he was righteous. R/W since he is a Night Watch character.
