After several weeks of careful observation I think I figured out some element. What I first thought was simple dismorphic differences between individuals seems to be a way to distinguish males and females. Men are shorter, stout and thick while women are slenderer but as much brawly as them… Even if I only eared orders coming from the women, troops seems to be male and female wearing both hoods and carrying maces and huge shields… Only one thing is clear, this nation is preparing for a conflict. Do they fear us or should we fear them ?
