Siyat Dragons are extremely smart and have an excellent memory. They are very quick and will often dive through the air making chirps and calls for attention if they feel ignored. Siyat dragons are herbivores and need to eat a lot to make up for all the energy they use with their excitable nature. Groups of Siyat Dragons have a hierarchical structure based on the color of their markings. It is thought that the social status of a dragon is determined by its incubation period—in addition to having different coloration, dragons allowed more time to develop are considered wiser and of higher status.

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.

Radical is the "chewy center" of his group. Though the nickname is playful, the other dragons do like and respect him for his empathy and brains, even if he insists he was the stupid one back when he lived among other siyats. He lacks combat experience and limits himself to planning and motivational speeches. When communicating with other groups or people, Radical never says "I don't know": when he doesn't know the answer to a question, he'll either say all he knows, say something that is too vague to be meaningful, or evade the question by changing the subject. Oftentimes, he'll talk smoothly and confidently enough that it takes a while for someone to notice that he doesn't know. Only his group members know if "Radical" is his real name.
