Nocturne Dragons are a strange breed. Whenever light strikes their bodies, they are frozen in whatever position they were in. This leaves them vulnerable and they rely on camouflage to keep themselves safe. They are often mistaken for statues when in this frozen state, but Nocturne dragons do not actually turn into stone. Rather, they merely idle until the sun goes down. At night, these dragons come to life, proving themselves to be powerful fliers, although little else is known about their true behavior.

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.

Indilmiruvor is a mischievous and playful young adult. Whisperer, the enchantress, promised Indilmiruvor that someday she'd find a female Nocturne Dragon. Until then, Indilmiruvor will just play with the hatchlings and tease the more serious adults. He often bites them on the tail then flies away, laughing. Once the sun came up while he was flying. He crashed to the ground, and Hinaeva I Vilya and his friend, Anguloce, found him. They dragged him back to the cave and asked Ranenen, Hinaeva I Vilya's mother, what the 'strange creature' was. Ranenen laughed and told them that the 'strange creature' was their playmate, Indilmiruvor.
