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.

Bruce the Other Guy is both one of the most sought after Lindwurms and also one of the most avoided.

Bruce is a very kindhearted Lindwurm who constantly helps others. He doesn't consider himself a good listener and prefers to spend time alone studying how the universe works. He especially likes to study how to heal dragons and is considered a healer by some. Bruce is extremely shy and socially awkward.

The Other Guy, who dragons have nicknamed Hulk and Big Brute, seems to have no other goal in life than to destroy. His only emotion appears to be anger and hate. The Other Guy does not disturb Bruce most of the time, but if he thinks Bruce is slightly irritated he will attack whoever is causing the irritation. The Other Guy does have friends but it takes a lot to get through his huge layer of anger. Once you become The Other Guy's friend, he will risk everything for you.

Bruce and The Other Guy do act in complete unison if there is either a clan or worldwide threat.
