Green Dragons

Green Dragons have become fairly widespread but they have not adapted to their new ways since the loss of Tiamat. They were once her schemers and without her to guard them they have become paranoid and timid creatures. They seek out forests away from powerful creatures and establish their lairs, burrows deep within the ground that hide them from dangers. One may not even know a Green Dragon is within an area unless it is an ancient, they hide their lairs and ways very well. 
Some like Liezzen have become "Guardian Spirits" of certain sites in exchange for offerings of food or other items.
