Cyrios Mountains

The Cyrios Mountains extend from the Frigid Depths to the Wuyun Gates and separate the Menagerie Coast and the Lushgut Forest from the rest of Wildemount.

Mount Mentiri
Northwest of Kamordah, rising above the surrounding mountains, lies the deep red-orange Mount Mentiri. It is widely believed to be the source of the geothermal activity in the area. Isharnai the Prism Sage lives in a hut at its base. The swamps surrounding the area are inhabited by vast numbers of husk zombies, the remains of those killed when the Julous Dominion wiped out a sect of worshipers of the Twilight Phoenix. The sect had a longstanding belief that Mount Mentiri was either the Phoenix's home, or what it became when eventually laid to rest, thus explaining the geothermal activity in the vicinity.

Trivia
In the Nine Hells, the underground prison beneath the City of Dis is called the Mentiri. That the underground prison for Asmodeus's mount is called Mount Mentiri is presumably not a mere coincidence.
