Despite their massive size, Lacula Dragons are supremely stealthy creatures that rely on cunning wit to overcome the disadvantage of their large, flightless bodies. These dragons carve their homes into wet caves along the shores of sea cliffs, and use their resourcefulness to trap prey into the corners of large labyrinths of their own design. Typical prey often includes other dragons of medium size, but Lacula Dragons have been known to overcome larger creatures through sheer ambition and force of will. Their bite is often fatal to smaller creatures due to the potent venom in their hooked fangs, which is capable of paralyzing even the largest of adversaries. Although these dragons are solitary in nature and only meet for breeding purposes, a Lacula may be convinced to share its territory with another dragon if advantageous. In this case, the bonds a Lacula forms are everlasting, and any companions of a Lacula should count themselves lucky to have such a dragon willing to protect them.

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.

Iumbre is a sassy and witty beast of the treacherous shoreline cliffs. She gives herself far more credit than she deserves, thinking rather highly of skills she doesn't have and boasting about her hunting strategies which mostly involve plucking dead things that wash up on shore. She has no permanent den of her own, spending her days surfing about the waves and eating whatever she finds. She considers the Lacula dragon Uthrejax to be her boyfriend rather than an actual mate, despite the fact that she's raised many of his children, and insists on living a life of solitude.
