Speckle-Throated Dragons are an active, playful breed. They are easily excited and rarely remain still, spending much of their time in the air. Living in groups of up to sixty dragons, they nest in open plains and at the bases of mountains. Their speckled throats are their most distinctive feature, as well as the loud, echoing call they produce to communicate with one another. Female Speckle-Throats are slightly smaller than males and lack a head crest. However, they are swifter and more agile and prefer to hunt in small groups in order to take down prey.

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.

Rose always thought she had a strange first name. She wasn't sure why her parents had chosen it, but she was certain it was unique. At least, until she met Agent Trevelyan. The two dragons bonded over the odd coincidence, and began introducing themselves as the Agents. Other dragons frequently asked what they were agents of. "No, our names are Agent Rose and Agent Trevelyan—we're the Agents, see." This explanation was repeated from dragon to dragon and distorted slightly over time, and Rose and Trevelyan became known as the Agensee. They didn't seem to mind, and treated the Agensee as a sort of club. Rose's curious nature combined with Trevelyan's temper meant the Agents found themselves frequently in over their heads. Nevertheless, they remain good friends, and hope to find other 'Agents' in the future.
