An almost strictly nocturnal breed, Ciriax Lindwyrms are especially attuned to the moons’ cycles. They spend nights patrolling the edges of their territory, aggressively fending off intruders while they feast on their prey. After two or three nights of feeding, often around the time of at least one full moon, Ciriax Lindwyrms retreat to the recesses of their cave or underground homes. These dragons make it particularly difficult to travel on nights that are well-lit by moonlight, often to an unsuspecting adventurer’s dismay.

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.

Two-headed dragons are unique enough to deserve a separate classification from ordinary dragons. They have two necks, two brains, two mouths, but one stomach and one main body. The two heads usually work together, but there are times when they will fight each other, snapping back and forth. Their unique anatomy prevents them from breeding with single-headed dragons.

Sensory and his sister, Sensibility, run a clinic for dragons in need of constant medical attention. Sensory's job is to work with these dragons on an psychological and emotional level. He is essentially their therapist. As such, Sensory is a fantastic listener and pays close attention to what his patients say to him. Like his sister, he is pretty emotionally detached himself and doesn't seem to react to any external stimuli. He's heard the saddest, most upsetting stories of all yet barely bats an eye. This would probably make him pretty bad at his job, and he can certainly be uncanny to encounter, but Sensory knows emotions better than anyone. He can read others with astounding accuracy, to the point where some accuse him of mind reading. He knows precisely what to tell his patients and how and will present to them a most perfect reaction to whatever they are feeling. Admittedly, however, Sensory tends to share in his sister's habit of treating patients like subjects for analysis.
