Well, I'll go back to some nation building. Furnish his pyrimad. Maybe during the next turn I will speed up weapon weapon innovation for his formation of a milliary. No one has thought of using Obsidian arrowheads or lined blades? Ironheart is volcanic?

EDIT: At least, no one has explicitly made obsidian yet.
