|Dragons crafted from Gemstones, like the Emerald Dragon, have many aspects that are unfamiliar to Dragon Keepers. For example, the Emerald Dragon often sticks out its tongue in what was thought to be a playful manner. However, this is sensory reaction; Emerald Dragons can only hear clearly when their tongue outside it's mouth, making them appear to be constantly teasing one another.
||Since Emerald Dragons are somewhat hard of hearing, they often are not able to roar to each other over large distances. However, they make up for this shortcoming by communicating with a language based on light reflected from their shimmering wings. Naturally, they are not as talkative at night.
|By the time they reach adulthood, Emerald Dragons already have massive wings, but they do not stop growing. Their wings are made of a natural mineral, which continues to accumulate and bond with organic material so long as they continue to live in terrestrial areas.
||Epic Emerald Dragons have a symbiotic relationship with the environment around them. The organic material from the nearby plants, rocks and earth helps to fortify Emerald Dragons' rocky exterior; meanwhile sunlight reflected off the wings of an Epic Emerald Dragon has properties that helps plant life grow at a rapid rate. Forests have been known to spring up seemingly overnight around Epic Emerald Dragons habitats.
