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.

The mate of Keepers, Rembrandt's egg was found alongside Keepers and taken into custody by soulskimmers, a simple village girl. When he matured, he instantly targeted soulskimmers as a prey wanting to test out his newly acquired strengths—speed and his long tail. This provoked Allegreto to defend her master and severely injure Rembrandts. Like Magnoli he was shunned by the other dragons living on soulskimmer's property. Even Keepers who was beginning to grow fond of him, ignored Rembrandts. While his wounds healed, soulskimnmers (accompanied by Keepers) often visited him, trying to regain his trust. Eventually he was welcomed back and named after the greatest artist that lived in the city of Farlem, Rembrandts. The reason for his name (according to soulskimmers) is that the blue strips around his body remind her of Rembrandt's (the artist) favorite color, blue.
