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.

Smaragdiliito is a speed-loving green dragon, but running inside the cave is not enough for him. His heart constantly longs for flying. He likes speeding through the air, and feeling the wind blowing all around his body. He often races with a skywing dragon called Waulish Tuulikello—even though he has never been fast enough to win. Smaragdiliito is an outdoor dragon who doesn't care much about staying inside the cave. He deeply loves his friends and family, and his nature is very kind and caring, but calls of the open sky are often too hard for him to oppose. His name "Smaragdiliito" is Finnish, and can be translated as "emerald glide". Smaragdiliito is partly named after his varied green colours, partly after his affection towards flying.
