Barbarians are raging because I didn't see a consensus either way and, after testing, determined that raging barbarians on noble difficulty were not an existential threat to competent players.
Acheron is off because he would utterly screw with the map design if he randomly spawned in the wrong place. That said, I wouldn't read too much into this setting...
I didn't give anyone the Starting Settler promotion, for balance and gameplay reasons.
Apologies if I forgot to give one of your warriors the bonus promotions (Heroic Defense 1 and Homeland). If you want to restart with the promotions added, I can send out a new starting turn. TBH I seriously doubt you'll need them, especially since you started with two warriors (as the Khazad always do).
