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.

People who know this dragon call her "Wolf in Sheep's Clothing", or Wisc for short. She finds dragons that are new to her land and manipulates them. She acts nice to them at first, but then she betrays them once they confide a secret in her. She uses that secret to blackmail them into giving up part of their hoard and makes them do odd jobs for her, like hunting.

Her only true friend is a daydream dragon called Duke Promise. She has been friends with him since he was a fledgling, and Wisc never had the heart to ever hurt him, because he is so nice to her and he is a very pure soul.
