Fang dragon

A fang dragon, also known as a gray dragon, was a type of dragon found in Faerûn.

Description
Fang dragons were poor flyers, with small muscled wings. Their eyes tended to be either red or orange. Their heads were edged with spikes or horns. Their bodies tended to be covered in bony plates that ended in spurs at the joints, and their tails were forked with scythe-like tips.

Ecology
These dragons were also susceptible to bouts of seemingly random outbursts of rage and violence. They typically spoke a small handful of languages, and they used this ability in order to negotiate their way out of situations that could result in difficult or even deadly battles.

They sometimes sealed up their lairs with boulders or other materials before leaving them, usually in the hunt for food, which they preferred to find far from their homes. Their diet consisted of flesh, of which they prefered that of intelligent animals.

History
Fang dragons were first encountered in the ruins of Myth Drannor, which has led to speculation that they were connected to the demonic inhabitants that resided there after its fall. They could also be found, as of 1372 DR, in the Starwood in Cormanthor, the Border Forest, Spiderhaunt Woods, and other forest areas of the Dalelands, the Moonsea and Sembia.

At some point, the goddess Tiamat chose to subject fang dragon eggs to a ritual that "improved" the hatchlings by giving them a breath weapon. After that point they were known almost soley as "gray dragons." She charged all gray dragons with purifying the species by killing any known fang dragons.

Combat
Fang dragons were skilled at physical combat, particularly because their bodies were so lethal. They had a tendency to "play" with their food. They did not have a breath weapon until Tiamat changed them, at which point the improved gray dragons had an acid breath weapon.
