Failed attempts to experiment with magic often result in transforming dragons into these hellish creatures. They are extremely dangerous, and will mindlessly kill any living creature without regard to friend or foe.

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.

I'm happy today is a zombie dragon that is actually, contradicting her name, not happy at all. She does not feel emotion and is normally at the back of the cave, chewing on rocks (She thinks they're hatchlings) and being feared by the other dragons.
