Feisty and energetic, Whiptail Dragons pride themselves on their speed and agility. It is not unusual to see several whiptails racing each other. Though fragile, they can easily evade attacks with their superior speed, and often use their long tails as a weapon, giving rise to their name.

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.

Archu is the clan's scout. He explores the surrounding area, dodging threats and obstacles, to find targets for raids and hunting. He locates any possible enemies, food sources, or other dragons. Never much for diplomacy, he has orders from Empirius to only find the targets, and leave any talking to someone else. However, Archu frequently disobeys and attacks the target for fun, and maybe some shinies.
