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.

Rot, like his name, is nasty and unpleasant. He acts like a feral beast, roaming on his own and lashing out at anyone that may try to approach. He is particularly aggressive, violently biting and stinging his foe until he believes they are no longer a threat before dashing away to find shelter. Rot does not trust easily, if at all. He is extremely paranoid of others and only really feels comfortable when he's hidden away. He prefers dark, dank places to hide. Rotting tree stumps, old logs, dark alcoves, all of these are perfect places for him to rest, if even for a short time. He also tends to wander at night, preferring the darkness to the much more exposing light.
