Royal Blue dragons are a nocturnal breed who prefer to live high in the mountains near slow-moving water that reflects the night sky. Although quite capable of defending themselves, they are peaceful by nature and will avoid a fight whenever possible.

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.

BluLu belongs to a very special elite troop of dragons within the clan. After overhearing the threats of another human to kidnap the human caretaker's Beloved, Dimar, they decided to form a personal guard and strike force, protecting Dimar whenever she was visiting and ready to venture forth and attack and destroy anyone who would dare to touch her when she was elsewhere.

BluLu is Dimar's personal aide whenever she is visiting, never leaving her side. Among all of the dragons of Herk's clan, he knows Dimar the best and he sometimes takes the liberty of inviting her to concerts of the Moonsilver Artists' Association to make her stay with the clan as enjoyable as possible.
