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.

I AM IT, otherwise referred to as "The chosen one", is thought of by his cavemates to be increasingly vain and something of a megalomaniac; however, when he says "I am it" what he's really referring to is his ever-present delusion that the whole cave is an eternal game of tag and that it's his job to "catch" the other dragons.

When he notices they aren't running from him—as the game dictates they should be—he figures they don't realize he's "it" and shouts it out so they know to start running (or flying, if they are capable of such).
