I have not played mid in a while, but in all the realms, there are 4 new named dragons. The main dragon is not there anymore, but these "adolescent" dragons have taken their place. They drop loot similar to the main dragon's, and are easier to kill (although not soloable).....depending on the level of the dragons, it can take 3-8 people to kill.
I have only been in that area twice, and have not seen them fly, but they do hit very hard.
