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.

Encryptions and her sister-head Codes are obsessed with security. So much so that they can't bring themselves to even talk straight. They constantly change their way to communicate, using methods they call rot13, twofish, or serpent. From an early age on it seemed as if only the one head ever knew what the other head meant.

That is until they met Riddles and Darkness. While Darkness kept to himself, Riddles became obsessed with the two dragonesses and quickly found out that he needed two "keys"—one for each head—to find a way into their minds and hearts. Now Riddles, Encryptions, and Codes live in a very happy relationship, while Darkness just—well—tags along.
