Dragons of the green flight are highly reclusive. While the greens are the most populous flight left on Azeroth, they are also the most difficult to find on the mortal realm. Green dragons are creatures of the Emerald Dream, the ethereal dreamworld that all life is a part of, and spend the vast majority of their lives within it. Time is meaningless inside the Dream and as a result the green dragonflight is extremely long-lived. Ysera's consorts in particular almost never emerge and are effectively immortal. Other flights often call greens "brothers and sisters of Dream," in respect to the realm from which they hail.
