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.

Green and Lean is sometimes singularly Green and Lean, and they are sometimes separately Green and Lean, respectively. Having been solitary for the majority of his life, he hasn't really thought about the singular-or-plural-individuals thing until one night, one of his prey asked this mostly useless but curious question, and Green and Lean were so distracted by it that they accidentally let their meal escape. Since then, Green and Lean has been inexplicably curious about how social beings interact and often skulks into towns and other populated administrative zones to observe everyone. Most of them are rightly scared of him, and he used to explain that they ought not to be because he's the type of dragon who hunts using stealth, and if they can see him, it means he's not on the hunt. They would still act bothered and make small unhappy sounds, so he's stopped answering and now just stares at them until they understand him and go back to their business.
