Ýhasin Mountain Range

The Ýhasin Mountain Range is a narrow band of mountains that is located at the northern edge of the Blýfónic Valley. It completely separates the Ýyr-Yožikut from the rest of the Valley. Alongside the Arbin Watershed in the west, the Nuzowli Mountain Range in the south, and the Aragnia Mountains in the east, the Ýhasin Mountain Range constitutes one of the four Wozalfisó-Blýfon, or Blýfonic Beasts, that surround and contribute greatly to the maintenance of the Amoŋot Desert and the Ðýmóš Plains, the two subregions of the Valley. 
Being the steepest and tallest of the four Wozalfisó-Blýfon, the Ýhasin Mountains contain the most mountain passes, at around 25.
