Peace dragons (Draco pacem) are very peaceful dragons. They are rare and are hated by War Dragons.
History
They have ended every war in recorded history. They have tried to do it peacefully, but like World War II, it wasn't possible, hence the atomic bomb. They oppose war dragons wherever the go, trying to keep peace between humans and dragons alike. Not much else is known about them.
Appearance
They are pure white in color with short spikes on their back. Their breath weapon is a white beam of pure energy. Nothing else is known as few sightings have been reported.
