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.

Ian is one of the many dragons rescued and nurtured by the wide ranging clan of humans founded by AnselaJonla. His egg was found in the desert sands and taken to a hatchery to be raised.

Once he matured, he found his lifemate, a Lumina dragon, among the other AnselaJonla dragons. In the tradition of the AnselaJonla flock, both dragons took the same name, Arkech, to pass down to any of their offspring that remained within the flock.

Ian is almost as much of a prankster as the Misfits. His pranks, however, revolve around the conveniently timed release of noxious gas from his body.

Playing pranks isn't the only use for his gas though. He found that he could use the gases his body produced to knock out his prey, or that he could release an especially large cloud against attackers.

After one little accident with this method, he soon learned to make sure that Gloria wasn't doing her "roaring pillar of flame" attack into the same area.
