Gilded Bloodscale Dragons often spend hours investigating every minute detail of caves, making sure their living spaces are arranged exactly how they like. They crave intellectual stimulation and get bored easily. As such, these dragons prefer to lure in their prey using their sharp minds rather than brute strength, often engaging in battles of wits between their two heads to determine how best to proceed. Seen as eccentric by other dragons, they are often shunned by all but their own kind.

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.

Chaos Theory was sent to Aquenee's cave as an egg by a young dragonkeeper, whom Aquenee has told him is named Dimar. Since then, he always believed that he had a certain, specific purpose for being brought here, but he never could figure out what it was. He lived in thought, constantly anticipating the day his purpose would emerge, watching as dragons treated each other with cruelty and violence. It came to him when a young Ice hatchling, named Judgement, began to say she needed followers to help her defeat and imprison the cold-hearted Vexen. Knowing well of Vexen's clever, intelligent nature, Theory soon realized that the intelligence of two interlocked minds would be almost crucial for that type of operation, and soon joined Judgement in her quest. With Theory at her side to plan and think critically on a whim, the revolution was a great success and definitely cut down the amount of crime in the cave. Theory now waits diligently for the day that his minds come in handy yet again.
