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.

A powerful sunset dragoness, Indigo RazorClaw is not one to cross. She is extremely fast, with very sharp claws, thus her name. However, she doesn't like mornings very much, and is often grumpy then. Indigo has only been outmatched in a race by two dragons so far, one being Wind Slicer, and the other, the fun-loving Early Dawn.  Realizing that she was no match for a whiptail dragoness, she made her rival Early Dawn, vowing to eventually defeat her in a race. Indigo's permanent mate is Embric. The two get along very well, and rarely argue.
