[X] Join in the celebration of the victory against Winter, and take the opportunity to ask after the history of the Thenns
-[X] What do they remember of the Dawn Age when they first settled these lands? Who led them?
-[X] Who set the Landwards? Also, can they tell us what the Landwards do? How are they maintained?
-[X] How did the lands change after the Wall was built? What did they see of how the Free Folk lost their heritage while the Thenns alone remained?
-[X] What is their memory of the Age of Heroes?
-[X] Ask of the Magnar, who he is, how he rose to become Magnar, etc.
-[X] Current Situation
--[X] What types of monsters have they encountered over the past few decades?
--[X] Ask about their relations with the various nearby clans, any notable people they're aware of as well as their rough locations, etc.
--[X] What lore have they retained for the creation of items of magic?
--[X] Talk about the coming Winter. What do the Thenns plan to do about it? In their own legends they settled after the Long Night's power had mostly passed, but now it comes again in full in a few scant years. And the Thenns stand closer to the heart of the Others' power than nearly every other tribe of man.
--[X] Tell them that you have an offer for every man, giant or other warm-blooded being in the north. A plot of land in a place where they will curse the heat, the ground is fertile and food is plenty for anyone who doesn't shy away from honest work to earn it. All they have to do for that is to accept the law of the land.
--[X] Especially invite their lorekeepers, godis or druids to send someone to your lands. You have a grand ritual in the honor of the gods planned and it would be a great occasion for them to witness. Doubly so because they pointed us to the best morsel for it.
---[X] In addition to any druids they may have, a few other Thenns the Magnar trusts (or possibly even the Magnar himself if he can be spared) would be equally welcomed as guests so they may see our lands with their own eyes.
--[X] Make it clear that you are not offering them shelter. You are gathering an army in the south. One that is even now being prepared for the night to come. And your idea is not to merely hold the Wall against the dead.
