Auratails are an exotic humanoid species, once hunted and prized as "jewelry" by a race of giants. Since then they have gained their independence, though the threat still looms. Among Auratails, there exists three subspecies; the Night Carriers, Day Carriers, and the ever elusive Twilights.

Each carries their respective aura in their glass tails. This aura also serves as their lifeblood, and they can only die if all the aura is drained from their body. This means they can live for hundreds of years. They can also conjure a wide variety of crystalline objects and weapons- both for leisure and self defence.
