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.

Intoku loves the sight of flowers, but due to the natural decaying force inherent to her breed, she rarely gets to see real flowers up close before they start to wither. Her cavern is filled with glass jars of dried petals and whole blossoms preserved in clear resins; these are the nearest Intoku can get to enjoying real flowers. Most of these objects come from traveling caravans that request Intoku's help through treacherous areas of her biome. The merchants will happily provide small floral trinkets to Intoku in exchange for her assistance keeping the path before their wagons clear, and while she doesn't interact with others often, Intoku is grateful for the small pieces of color she can keep in her home.
