@Boney not sure if you were just planning to add this after the purchase round, but just in case it was missed since the action itself did pas:
This past turn we took this action
-[] KAU: Hire educators to teach a language or group of languages to your scribes (Old World Languages)
So the languages section for the library should probably be updated from:
Scribes recruited from the human and Halfling population of Karak Eight Peaks. Languages known: Reikspiel, Tilean.
On that note since I was looking at that for a reason, do you guys think we should grab Vlag with the next library action? I imagine they would not scoff at our +6 Demons, various other Chaos gribble books as well as other foes like Greenskins, vampires and the undead.
