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.

Lemon Lime SP is quite a dare devil and enjoys flying into the mouths of volcanoes, especially if they are close to overflowing. Once she burned her one of her wings and couldn't fly for a month. During this period she met Never Trust Me. After spending some time together they bred and had one child. Now she doesn't see much of him and has taken to the skies. Lemon has shown signs of scale rot, but they always disappear before anyone has the courage to say something. The other dragons think she may see a magi, or have some unknown method of curing scale rot. But like telling her she has it, no one has the courage to ask this feisty dragon.
