Here there be Dragons
In the life of dark dragons are known as the most powerful beasts there is. Little is understood about dragons, except that they are terrifying creatures.
The dragons in reality are mostly made up from bahamut. These dragons will work towards the good of the world, whether that be for or against the other races. There are dragons of every variety able to either cross into this plane, or are already there inhabiting it.
The dragons in this realm are made up of bahamut's forces; a location to almost relax in the realms. See bahamut for more information about how he operates in this realm. In the icy tundra is where most of the forces will stay, it isn't unheard of for them to quietly roam to see how the realm is working, and if evil is present.
