Sophrosyne Dragons are a rare sight, typically making themselves known only to protect and heal the vulnerable. A visit from one serves as a reminder that kindness prevails, and that there’s always hope for positive change. While it is known that they possess the power to reverse botched spells, some claim they can even cure methodically-cast curses. This has never been formally documented, but these dragons have been seen arriving in the aftermath of violence, and the scars of tragedy seem to heal faster in their wake. The feathers of a Sophrosyne have thus become a symbol of perseverance and light in the face of darkness.

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.

Kind and gentle, Somnambulist's Wings is one of the many music-loving dragons that resides in the cave. Before he was in Kim's care, Somnambulist traveled to various places in search of a place to call home. Many of passersby would note that he's often surrounded or followed by somnambulists or that there's a large amount of them sighted shortly after he passes through an area. Because of this, he became the symbol of those types of people and was dubbed "the Summoner of Slumber". That was until one fateful day when he was attacked by a large group of hunters. These hunters were after the feathers of his kind because of the rumors surrounding them. Luckily, a large and fearsome Red Dragon (Meiko of the Vocaloids) chased the hunters away and stayed by his side until help had arrived. He was taken to the cave where most of Kim's dragons resided and was nursed back to health. He has lived there ever since, not as ruler of somnambulists, but as a helpful therapist for the dragons.
