Sunset Dragons are closely related to sunrise dragons. However, their behaviors differ greatly. Sunset Dragons generally live alone or in small packs. They are more active in the evening, hunting and performing all of their daily tasks as the sun sets.

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.

Lullaby Draekon, or, 'Can You Sing Me a Lullaby', is among the most musical dragons in his cave. He and several others have a small song group. His mate, Song Draekon (A Song That Only I Can Hear), is his singing partner. They enjoy going out at sunset as the Nocturne 'unfreezes' for the night, filling the air with dragonsong. When he was younger, he particularly took to the Sunset dragon in the cave, Song of the Bells. It was from him that Lullaby discovered his joy of singing. As a young dragon, he was lucky he had a nice voice, even then. It rivaled the voices of even those who were very experienced in the cave. He has a wide range in singing pitch, which is why he and his beloved mate are now the singing leaders of the musical group in the cave. When he isn't singing, he enjoys naps, especially in the cozy darkness of a quiet cave.
