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.

GrandOlive is big for an Olive Dragon, almost half again as big as any other dragon of his species in his group. He is certainly the largest Olive Dragon in his cave, but he's still small compared to most other types of dragons. He seems to need far more food to keep him going than others of his smaller breed, and he's always hunting. GrandOlive is a great hunter, and usually kills more than one small deer a week.
