Ice Dragon

Ice dragons (Draco glacie) are a gentle and beautiful species of dragon, well known for being friendly to humans yet aggressive towards their enemies.

History
The first ice dragons came about during the Ice Age. They evolved from the water dragons but their bodies had to adapt to a cold environment; eventually, they began to produce unique adaptations such as sharp ridges and spikes of ice coating their body to protect from predators and a breath weapon of freezing air to turn foes to ice.

The fire dragons of that time were primitive, cruel and evil. Their fire easily melted through the ice dragons' frozen scales, driving them into Antarctica and northern Russia; to this day they still live there in great numbers.

Appearance
Most ice dragons have long, serpentine bodies with four or six limbs. Their scales are nearly always a reflective white, blue or purplish color, though on rare occasions they can be silver. They have very small wings and large spikes across their bodies.

Because of their icy scales, spikes and claws, ice dragons can't survive in conditions above room temperature as they would begin to melt.

Subspecies
Ice Dragons proper are made, as the name suggests, from ice though they contain other materials for different parts of their body including snow for wings and some parts of their body. Snow dragons use snow to cover almost all of their scales and for their insides relying on ice only for structure. This leads to snow dragons being smaller as they do not have as much structural integrity but also being faster as they are lighter. The two can be differentiated as ice dragons glisten and are translucent.

Frost dragons are very different from both of their kin being almost non-corporeal like the Cloud Dragon. They have a few thin icy bones around which a cold mist forms. For this reason they are entirely bound to cold regions.
