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.

Tail God is not an actual god. In fact, he's an ordinary dragon. Back then, when humans first set sights on dragons, they were so shocked at these magnificent creatures, the humans decided to worship these magical creatures. They gave the name Tail God to this dragon because when he's excited, he usually whips his tail around. He also uses the tail as a mode of defense, if one dragon or human should come to attack him.
