Mount Vyzantium

Summary

The tallest mountain in the Thalassan Sphere, Mount Vyz (as it is widely known,) rises 41,000 feet above seat level and takes up most of the Island of Vyzantium. The Free City of Vyzantium is carved into its south side and Northfort into its north side.

Under Mount Vyz lies the Deep City of Undervyz, a dwarven city built on the ruins of Caer Draenok, an ancient dwarven civilization about which very little is known. The ancient city is so vast that much of it still hasn't been mapped. Even so, it fills up only a tiny fraction of the mountain's mass and connects to a largely unexplored cavern system called the Deep Below. In fact, the mountain is so riddled with caverns and passages that its nickname is "the big anthill."
