Perhaps the most majestic creature of the Flaming Tundra, the crown-of-flames deer is an oddity. The beasts sport fur white as snow and pale hooves, with eyes that glow a bright reddish-orange. A great pair of antlers sprout from their heads, even females; however, females have smaller ones. Unlike most creatures of the Flaming Tundra, which exhale fire fueled by their gas sacs, the crown-of-flames deer's gas sac's tubes extend into its skull, where tiny holes in the antlers steadily spew out an inferno that dons the creature's head like a crown, as its name suggests. Utilizing this, the deer can perform fiery headbutts on offenders. Feeding on gas grass, the deer form small groups, usually consisting of two mates and a child. Their antlers are prized trophies of the hunt, and, with enchantments, can be lit on fire even after the crown-of-flames deer is killed and the antlers severed.
