Black dragons are abusive, quick to anger, and resent intrusions of any kind. They like dismal surroundings, heavy vegetation, and prefer darkness to daylight. Although not as intelligent as other dragons, black dragons are instinctively cunning and malevolent.
At birth, a black dragons scales are thin, small, and glossy. But as the dragon ages, its scales become larger, thicker, and duller, which helps it camouflage itself in swamps and marshes. Black dragons speak their own tongue, a tongue common to all evil dragons, and 10% of hatchling black dragons have an ability to communicate with any intelligent creature. The chance to possess this ability increases 5% per age category of the dragon.
