Quick pitch: Containing the tallest peaks on Rozarria, the Aegian Mountains create one of the most treacherous natural borders in the world. Perilous crevasses and sheer cliffs make traversing the mountains deadly enough, regardless of the blinding snowstorms and frigid temperatures the Icewastes are already so well known for. Those seeking to reach the Murmuring Plains to the north are better off circumventing the mountains entirely by boat.
