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.

Gray Unitedflag, like other two-headed creatures in the cave, is actually two souls in the same body. The two heads share the same name that is used to mention or call both heads. Gray also has other two names, Gra and Ray, which refer to his left and right heads respectively. He is quite straightforward, and loves to fight with other dragons. He has beaten most of the dragons in nearby areas. The only ten dragons he can't beat are members of the Ten Dasoul Warriors, the strongest dragons in that area. The group consists of nine males and a female, who has been his rival for two centuries: Narasha, the Gilded Bloodscale Dragon. The two dragons always fight each other in order to prove their powers at least twice a week. Nobody can judge which one is stronger, as their strengths and weaknesses are almost polar opposites. Gray is notable for his powerful attacks, but lacks strategies, and often falls for Narasha's traps.
