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.

Swift Delta is an energetic dragon, which is no surprise since he is a Whiptail. His large social group, his love of speed, and the fact that many females adore him is also of no surprise. The unique thing about him is that his father is a magi dragon, hence Swift gained a bit of magic powers. And when he was little, he preferred a female hatchling's company rather than a male hatchling's, hence his human thought that he was a female before his gender was shown. This preference led to him finding his mate, Terrae Delta. At first, he didn't really enjoy her company (while on a playdate) because she was so slow in doing things. She was only enjoying what she was doing, that's why she likes to take time in doing the things she does. One day, Swift was racing all over the cave while Terrae was lecturing him. She stopped Swift just in time before he was about to crash into Sky Delta, the leader of the Delta dragons. He then fell for her. Swift Delta is a born member of Delta Clan.
