The Elux Lucis are a nocturnal breed of dragon found in the far north and at the peaks of particularly tall mountain ranges. During the day, their deep indigo scales easily conceal them among the trees, but at night, their remarkable iridescence is revealed; even the faintest starlight reflects off of their bodies in a dazzling display of colors. In flight, they almost resemble living auroras soaring across the night sky. During the winter, flocks of Elux Lucis fly south to hatch and raise their young. This annual migration is well known for filling the night sky with a display of reflected moonlight and starlight so vibrant it seems as though the northern lights themselves have wandered south.

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.

Iruducis likes colors. She likes when things have many colors—the more, the better! Her portion of clan territory is garishly decorated, and the big sign with her name on it is splattered with every color she could get her hands on, with paints from 14 locations. After rainfall, she'll stay up late to look at rainbows, and she often dozes off during the night when she hasn't slept well. Her favorite human settlement is Zacheng, mainly because that was the first human-inhabited place she went to during one of her childhood migrations, so there's a sentimentality to it. It's also because over time, Zacheng had places undergo multiple renovations, lots of humans coming and going, things destroyed and new things built, stuff becoming trendy and stuff going obsolete. The town is really colorful with lots of architectural styles and so many flowers and murals. Iruducis hopes that the humans will keep getting along and remain peaceful, and continue to add colorful things to their town.
