So, the typical view of dragons in different regions are basically identical scaled beasts, color-coded by what element they breathe out and living in locations appropriate to those elements. Red dragons that breathe fire who live in volcanos, blue or white ice dragons who live in the frozen wastes, and so forth. This makes sense -- we use our thick scales for defense, but want little in the way of insulation because those of us who live in our ancestral homes are surrounded by our natural element.

There are some interesting exceptions, however.

Take, for example, the Polar Ignidragon. They're descended from the fire dragons in warmer locales, who realized their fire breath would give them an advantage in locales that rarely see heat. They've formed a layer of enchanted fat as an insulator to keep their bodies warm enough to keep the cold from extinguishing their inner flame -- Dragonite's look was actually modeled after the Polar Ignidragon. The flames they breathe are smaller and less warm than their ancestors, but they're more than warm enough to give them an advantage.

My friend Thraxxor is a Polar Ignidragon. Here we are visiting Alaska together. Yes, the rest of this lecture is going to be my vacation photos, why do you ask?
