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.

A peculiar pair of heads on a Lindwurm, Rea is the calmer of the two whilst Wake is the more impulsive of the duo. They are the sixth dragon of the Trial By Music clan.

Their song starts off joyous, as the newbie protagonist had won his first trial. However, this happiness doesn't last, as he would soon discover his mentor had been slain and her sister accused with her murder. This song changes so quickly from happiness to suspense and mournfulness that it almost gives folks a mood whiplash. Their song has three vocalists needed.

When off stage, Rea is often noticed talking with Overture or Mr. Fourth Alice, much to his twin brother's annoyance. Wake, on the other hand, prefers to jam out with the Vocaloid and DDR clans, which causes Rea constant headaches.
