I do not understand how Oromeax gets where he is going and also manages to breathe at the ice wall from top to bottom. He cannot fly west because the wall goes up to the Victory Zone roof. How does he get above the ice wall to breathe at the entire length from top to bottom?
Brrrr will back up to 100N70E, possibly provoking an AoO, then put a wall of coldfire somewhere. If, as I am assuming, it is solid like a wall of ice, it will be placed from 95N0E to 95N40E, fifty feet high. If is not solid, like a wall of fire, it will be placed from 90N35E to 120N35E, facing east.
