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.

Like her name suggests, Brook's primary element is water despite the fact that she has all the powers of the Storm dragon; just like her forebears.  Like her mother she churns the clouds and produces rain...though she has been known to take her magic to extremes and cause floods in the valley.  Thus Brook has been advised to only concentrate on water magic, in which her father trains as well.  Her personality is as outgoing and challenging as any of the other Storm dragons, more so due to her father's lineage, but it is more often that her bouts of anger are just mere accidents.
