Royal Blue dragons are a nocturnal breed who prefer to live high in the mountains near slow-moving water that reflects the night sky. Although quite capable of defending themselves, they are peaceful by nature and will avoid a fight whenever possible.

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.

Kratos is powerful and devoted to serving the High Family as a member of the Posluga. Living in the Mountains of Elgar, in a cave on the plateau of the mountain, Oulerun, Kratos shares his brethren's low view of the other living creatures in Elgar. However, he respects those that show strength, especially in times of difficulty. For this reason, he finds it amusing to stay by the side of Alke, representation of Courage in the Posluga. Kratos can be prideful, but he shows this by acting regal towards his fellow Posluga and those in the High Family. He rarely loses his calm and doesn't often get involved in the common feuds that take place between the others living on Oulerun. However, Kratos has no qualms with fighting others, especially if he is being commanded to do so by Chaos, leader of the High Family. Kratos represents Strength in the Posluga.
