Yellow-Crowned Dragons are found in the hottest, driest regions of the desert. Although they thrive in these conditions, they do very poorly in cold or humid climates. These dragons are very fast fliers and skilled hunters, and usually feed on small, quick desert antelope. Yellow-Crowned Dragons are diurnal, and spend the night in underground burrows they dig or steal from other creatures. They are often seen out sunning themselves in the early morning sun, waiting for the heat of the day to set in.

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.

Tat grew up in his mother's lair and early on learned that, while cats in general made for a good meal, Nall certainly didn't. His mum's feisty little pet and the young hatchling basically raised each other, mutually teaching one another the limits of another creature's patience through teeth and claws.

To this day Tat still feels the overwhelming desire to love and hug certain furry mammals to bits if he encounters an especially spunky feline and there are one or two mountain lions in the area he has encountered several times without ever eating them—although that might actually be kinder.
