Tetra Dragons are often found in large groups. They are very social both with their own species and with others. Tetra Dragons are very active and change locations quite frequently. Males defend small parts of territory within the groups but major conflicts rarely occur. Tetra Dragons prefer territory with lots of natural hiding places and can be skittish.

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.

Opal is a host through-and-through. He's a people- er, dragon pleaser who always needs to have everything planned out. He's the kind of guy who needs everything to be perfect, meaning he is prone to stressing himself out over trivial things. He is good about keeping his neurosis under control, however. When he's in action, having guests and throwing lavish parties, one would never be able to tell he were under any pressure at all. Of course, those that know him well enough know the signs of his cracking and fatigue. He is lucky to have others around him who know how to support him, even when he tends to be stubborn to except help. Opal always wants to take care of everyone, so he isn't always comfortable with others taking care of him. He has been working on getting rid of such self-destructive feelings, but such a process is not a simple one. Still, Opal is incredibly kind, caring, and accommodating. He's quick to accept and slow to judge others, acting less skittish than other Tetra.
