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.

Rachel Genesis was born to Laban Genesis and Adinah Genesis. Growing up, she blossomed into an unparalleled beauty of the Genesis Clan. However, her sister became known as one of the ugliest. Rachel received many Fog gentlemen callers, but none were good enough for her until she met Jacob Genesis. She was heartbroken when he took Leah as his wife instead, but soon realized that she was his true love after all when he toiled for seven years to earn her hand in marriage as well.

In the beginning of the marriage, she quickly realized that she could not produce offspring, but her sister had already produced many sons. In her severe jealousy, she began using a surrogate mother to provide sons for Jacob.

After many years, she finally produced a son named Joseph Genesis. When Joseph disappeared, she also produced a second son named Benjamin Genesis.

Rachel Genesis is a jealous and spoiled dragon who has very little regard for her sister. She is vain and basks in her husband's attention.
