Isohedrus

Isohedrus is an evil white dragon. The Wafflecrew had just escaped Barovia and were wandering in a blizzard. They spotted Isohedrus and took shelter in a lodge.

Much later, when the group came to the frost giant village of Kronenheim, they fought Isohedrus. Artus Cimber turned the dragon into an ice statue with flesh to ice.
