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.

Sisupussi is an extremely feisty whiptail dragon who never gives up. She does what she wants to do, goes where she wants to go to and spends her time with whoever she wants to spend it with. Her huge pride helps her win in races, but it also lets her down whenever she loses. She hates losing, and usually does anything she can to avoid it. However, most often she is victorious. Her name "Sisupussi" is a Finnish expression for a person who has lots of obstinacy.
