Olive Dragons are a small, forest-dwelling breed, rarely growing much larger than the average sheep. When alarmed, they can erect a long row of venomous spines on their back, serving to warn any potential predators that Olives are not a good choice for a meal. While not strong enough to kill anything larger than a small deer, their venom causes an extremely painful reaction and necrosis at the bite site, sometimes causing the flesh to rot and limbs to fall off.

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.

Disease has always been on the bad side of other dragons. It's just that she can't control her venom and just ends up hurting the dragons she wanted to communicate with. Well, alright—she can control it, but only for a short time because the venom starts to overflow and she has to dispose of it.

Of course she hunts almost all the day to use up the venom, but it never ends. It seems it was a defect at birth that has brought her to this sad state. She usually gets up from sleep in a puddle of her own venom, but it doesn't hurt her, only the ground. She always is so sad to be cast away from others because of this nonsense, but hopes she can share her faith with and another poor, misunderstood soul.
