Brimstone Dragons live in dry arid areas such as deserts where they feed mainly on sheep, goats and the occasional camel. Their favorite habitat is ideally situated close to the wastelands around active volcanoes. This is due to an important part of their diet—sulfur, which they obtain from deposits near volcanic gas vents. Instead of fire, these dragons use the sulfur they ingest to create a noxious gas which they store in their large throat pouches. When in danger, this gas is released in a large cloud. They also eat other mineral rich substances—including charcoal—and will drink the mineral rich (but slightly acidic) water commonly found in deserts and volcanic regions.

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.

HungryBrimstone is a Brimstone Dragon who is always hungry. Her favorite food is camel, and she mostly preys upon trade caravans. She never does more than scratch the humans as she tosses them out of the way so she can gobble up their camels. She doesn't care for the taste of human at all. She will eat the occasional horse, but she greatly prefers the camels. She likes to cover herself in a huge cloud of noxious gas as she eats, to keep the humans from attacking her. HungryBrimstone likes to keep most of the trade goods from off the camels to add to her hoard.
