Green Dragon
From DALpedia
Green Dragons are perhaps the most generic dragon, yet surprisingly they haven't appeared too much in Dark Age Legends. Green Dragons however have been known to have the ability of various kinds of elemental magic. However many of them, don't have any fire-breathing or magically abilities what-so-ever.
For the most part only small drake versions of them, and one wyvern sized dragon was being rode on by General Roland of the Blue Minotaur. It was not until Wilham appeared and summoned one of these mighty lizards was when we got to see a full grown one in action.
