Seinan is PMK's southwest region. It is unofficially divided in two smaller areas, High Seinan, and Lower Seinan. This divition is done because of a natural occurance in the regions geology. High Seinan is all of that which lies on top of the Seinan Plateau, a high ground that stands over 500m higher than Lower Seinan.
Lower seinan is a prolific area, with a wonderfull sight. The calm Mist River runs across it from Seinan Plateu into the sea, making it a farming paradise. Terrice City is a dedicated place where food for the whole PMK, and most of the Pokemon World, is grown.
