It's pretty cool. I've been learning python so it was pretty easy. My troop tree is Serf --> Huskarl --> Hirdman or mounted Hirdman ---> Vanhere or Vanherse. The lords are "Vanjarls". Then I just took a few cities from another faction and gave them their little place in the world
.
I want to do arco next, but I am having a hard time finding appropriate armor and shields.
