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