Dragons

History
Dragons originated within the core of Earth, made by Azazel. Originally, Leviathan was supposed to be a project to carry out murders. Instead, Leviathan gained a mind of his own and set off to be free of the bonds that held him to his "father".

Over the spans of thousands of years, dragons began to flourish. Medieval times had changed this, unfortunately. During these dark times, the dragons hid. Otherwise they would be killed. The only dragon that remained out of the shadows was Leviathan. Ultimately it got him banished to the sea.

Once medieval times passed, dragons began to flourish once again, creating new breeds of dragon as well. Some had wings, while others did not. And they all had different elements.

Fire
Fire dragons are the original dragons. They are all born to heat. Leviathan is the only truly black dragon. The other fire dragons are red, orange, or yellow. They also have an extremely horrible temper.

Air
These dragons are born anywhere that open air can get to them. Most are usually born in high up places, like trees.

Storm
A branch of air dragons. These guys can only be hatched when a storm erupts. Otherwise, they'll just be air dragons.

Water
These guys are born in water, obviously. They do not have wings like some of their relatives. Instead, they are born with flippers.

Ice
A branch off water. Normally they are born in water that's freezing cold, such as snow. They also do not have wings.

Earth
They are born to the earth and very often mistaken as lizards, as this is what a normal earth dragon looks like. All they really are is giant lizards. There have been other types of earth dragon sighted, but aren't as known to humans.

Sand
Whether a beach or desert, they can only be born in the sand. These ones are actually really hard to spot because they are the smallest of all the dragons.

Nature
They are usually born in thick vegitation. More of these ones have been spotted in China, hence the "oriental dragon".

Plasma
Or space dragon. These dragons are rare because they can only be born in space.

Light
These dragons can only hatch when the sun is directly over them. Being a branch of plasma, they are fairly rare as well.

Shadow
Also a branch of plasma and can only be born during a new moon.

Guardian
These ones aren't born. Each species has select few to be sure the eggs hatched as planned.
