The New Andes Mountains are the tallest mountain range on San Lucas. They bisect the New Andes/Gangani continent from western to eastern shores, and even continue as underwater ranges for hundreds of kilometers into the twin oceans surrounding the continent. They are tectonically-active on their northern face, with several living volcanoes slowly encroaching onto the surrounding highlands. Extinct volcanoes and jagged mountains dominate the southern edges looking over the lowland rainforests. It is a wild and treacherous area, with deep mountain valleys the only link between the northern forests and the southern jungles. Those valleys and the roads built into them are what the Gangani used to conquer the north, and are still major highways of trade to this day.
