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.

Kaku Ma'at's name comes from the ancient Egyptian word for 'darkness' and the name of the ancient Egyptian goddess of truth.

Kaku is the second eldest dragon in the cave, and he makes sure everyone else knows it. While he is gruff, he has his softer side but it may take some time in order to see it. He seems to have feelings for Nefer Ma'at, one of the other dragons but if this is brought up, he would deny it and the questioner would receive one of his glares.

He does his best to avoid being around the hatchlings as he says that they annoy him but he fights a losing battle. He is a thing of awe among the young and they follow him around at every given opportunity.
