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.

Abandoned as soon as she was laid, Lucky was placed in a cave full of abandoned eggs. Fortunately, she was soon picked out and brought back to the cave where she was hatched and raised. She was raised with three dragons whom she calls her siblings: one brother, Xavier, and two sisters, Quinn and Emmalyn. She was always much smaller than her siblings but was rarely picked on because of this. Instead, her larger litter-mates often carried her around for fun. Lucky, named for her birth name which contained her master's "lucky number", 39, enjoys playing with hatchlings and having races with her brother and sisters.
