Caligene Dragons have long been considered omens of death—reinforced by the skeletal markings on their bodies. They exert a malignant force on the world around them, causing other living things to slowly waste away in their presence. Caligenes favor the seasons of summer and autumn, disappearing entirely from the forests they inhabit during winter and spring. These malevolent dragons are physically weak, though this is countered by their natural stealthiness and alarming speed—enabling them to close in on large targets quickly and silently to create ambushes from which prey cannot escape.

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.

Mercy to the Dying spends most of her time tending to the ill and badly beaten dragons that the medical dragons can't save. Some dragons are beyond help, unfortunately.

Mercy to the Dying lays herself close to them, and by talking to them, preening them, and generally spending time attending to their needs, she tries to make their last moments as happy and calm as possible. By using her innate ability to sap the living essence out of existing things, she speeds along the process of death and makes it faster and more painless than it would've been had she not stepped in.

She is a very jovial and conversational dragon.
