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.

Caligenes are unfortunately unable to deactivate their draining powers, and Calilily is a prime example of the problems this causes. She loves flowers of all kinds, but when she lingers to admire them they wither under her aura. When she collects dried plants for arrangements, they soon crumble into dust. She is searching for a cassare who can save her from herself, but many mistakenly believe her powers can harm them despite their antimagic and flee, leaving her alone and desperate. It is a frustrating existence, often leading her to such frustration that she devolves to violence. Her outbursts only increase others' association of her with death, which in turn worsens her exasperation.
