Green Dragons are also sometimes called “earth” dragons. They usually live deep within caves, and have power over the earth. They are capable of launching boulders at high speeds, and can cause earthquakes by slamming down onto the ground.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Ereshkigal the Terrene is one of the quietest dragons in the Ruda Clan. She barely communicates, and it's not uncommon for her to go through a whole day without a single word. This does not come out of antisocial tendencies, however. It's only because she has nothing to say. Ereshkigal has a slight inferiority complex: she believes that she's only "average." She cannot lead like Alexandros the Unmoving, swim with ease like Tethys the Silent, or even match the energy of Suvi the Warm. This is not true in the eyes of Tlaloc the Proud, however. He thinks she's perfect the way she is and has always been there for her whenever she needed someone to make her feel better. She does wish, however, that he'd stop exaggerating her good qualities and accomplishments. Despite what Tlaloc says, Ereshkigal did not create the moon.
