Blue-Banded Dragons are found primarily in mountainous regions with lots of precipitation. Although terrestrial, they are most often sighted near running water and feed mostly on fish. Females are very social and form tight-knit family groups, while males are strictly solitary and will fight any other dragons that enter their territory outside of breeding season. For this reason, females tend to drive males away when they are not ready to mate, or when they are caring for hatchlings. The amount of striping varies greatly from individual to individual, with some dragons having only faint dark streaks on their sides and others appearing to be almost entirely dark blue with paler markings.

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.

Long ago, during a particularly long and devastating drought, three sisters made a deal with a Gray Dragon at the mountain's peak. He provided the rain that made their rivers run, but for some reason he stopped doing so without warning. He agreed to continue making rain, so long as the sisters served him when he called upon them. This was fine and well until his requests turned violent. The sisters refused and the Gray Dragon revoked his gift.

Nami would not allow her sisters to suffer. She sought the help of the Banni-ghymn, learning from them an ancient magic known as "Tidecalling". It relied on using the moon's power to control water, be it from the land or sky. Nami used this knowledge to draw rain down from the clouds.

High in the mountains, the Tidecaller spends her days in relative peace. Her sisters protect her, knowing that without her, the rivers would run dry again.

It is said that the Gray Dragon hunts for her, bitter that Nami took his place and broke the deal.
