Ziyero Ridge, also called Zigero Range, was a mountain range running through Koguryo in Koryo.[2][1][note 1]


The vast Dang Caverns lay beneath the range's northern tip.[2]


The mountains were heavily populated by foo dogs, foo lions, and griffons. It was not uncommon for dauntless folk to try to steal a pup, cub, or egg of these creatures in order to raise it as a dangerous yet loyal mount.[3]



  1. The range is called "Ziyero Ridge" in the Kara-Tur: The Eastern Realms but "Zigero Range" in The Forgotten Realms Atlas. The latter name is presumed to be in error, but they may represent different parts of the mountains.
