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.
Naurus is the only male Brimstone on SL's scroll. However, he doesn't particularly care. Naurus doesn't seem care about a lot of things.
Huddled deep in the volcanic plains that tower just west of the cave, Naurus lives in near solitude. The second Brimstone, Eries, occasionally drops by to eat her fill of sulfur, a vital part of a Brimstone's diet, but she rarely stays long. If she does, Naurus usually chases her off.
Many dragons try to avoid Naurus when he does decide to make an appearance in the cave. His noxious breath makes even the Magma Dragons wheeze. This is one of the many reasons he keeps away.
The only dragon capable and willing enough to stand Naurus is his mate, Roulette. The ash-eating Grave Dragon enjoys, if it can even be described as such, creating meals out of seemingly nothing for the Brimstone. And he doesn't mind her creepiness, mostly because he just doesn't care. About anything. Except maybe Roulette.
