Caligene Dragons have long been considered omens of death—reinforced by the skeletal markings on their bodies. They exert a malignant force on the world around them, causing other living things to slowly waste away in their presence. Caligenes favor the seasons of summer and autumn, disappearing entirely from the forests they inhabit during winter and spring. These malevolent dragons are physically weak, though this is countered by their natural stealthiness and alarming speed—enabling them to close in on large targets quickly and silently to create ambushes from which prey cannot escape.

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.

Like her pack-sister Nepenthe, Rafflesia loves the steamy, dark tangle of a dense tropical forest. As a fellow Alpha Female of the Revenga tribe-pack, she could just as easily have her own jungle court, but she's much more solitary, preferring to explore the depths of the tangled wood. Rafflesia loves to stalk and pursue the most challenging prey available using one-hit-kill ambush tactics and doesn't attack until she's figured out the target's weaknesses. When she's stalking a male dragon and doesn't find a serious weakness quickly, she tends to become infatuated, and uses her guile to lure the male into dallying with her long enough to give her an egg. A really powerful male may become a favorite to whom she returns more than once. Her favorites find her both alluring and frightening, like a succubus tempting them into delicious yet very real danger. It's said that she has even seduced one of the most respected of the elder Silver dragons. This is a minor scandal.
