Storm Dragons are the masters of the skies. They are excellent fliers and land only to rest and eat. In addition, they have full control of the weather. They are very hot-tempered and easily angered. They will attack any human that bothers them, conjuring strong winds and dangerous lightning.

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.

Dog Star Sirius is among those dragons who loves to watch the midnight skies while flying. His own star, Sirius, is his own pride and joy. He loves to look at it when the full moon it out and its light make his star shine even brighter. The reason why his name is also Dog Star Sirius, is because the star, Sirius, is nicknamed Dog Star from its constellation, Canis Major. Dog Star Sirius loves his star because it's the brightest star in the night sky. Dog Star Sirius roams through the sky throughout the whole day until the sunset is almost at an end; when the stars start to come out. His silver scales remind him about the color of the stars as they first appear in the night sky, and when they are almost gone. When he flies through the night sky, his wings blend in with that of the black sky of night. When he flies into the moon, his silhouette creates a gap in the moonlight that resembles his figure.
