In the ancient times of the Dragons when humans came. People who had studied Draconic Magic and studied the Language of the Draconic were know as either the Draconic Mages or The Dragon Lords. They draw their power and strength from their dragons. On the day of their Dragon's Birth the dragon will mark them either on their hand or another party of their body persay their forehead chest or legs. This gives them Access to their Dragon's Magic and Might. A Dragon Lord that Raises a Great Dragon will have might and power beyond most. To use the magic you can use either the Language of the elves or you can use the Language of the Dragon's. There are many incantation for the dragon power there are even some dragon lords that are born of a Dragon and a Human these are Hybread Dragon Lords and they can use strong dragon magic.
[Some incantation will be provided when I can remember some also some more history on the DragonLords]
