Black Dragon

Black dragons, also known as skull dragons, were far and away the most vile tempered and cruel of all chromatic dragons. They were solitary creatures that lived in the swamps and marshlands all around Toril, from the Flooded Forest in Sembia to the jungles of Chult.
The most evil-tempered and vile of the chromatic dragons, black dragons collect the wreckage and treasures of fallen peoples. These dragons loathe seeing the weak prosper and revel in the collapse of humanoid kingdoms. They make their homes in fetid swamps and crumbling ruins where kingdoms once stood.
With deep-socketed eyes and broad nasal openings, a black dragon's face resembles a skull. Its curving, segmented horns are bone-colored near the base and darken to dead black at the tips. As a black dragon ages, the flesh around its horns and cheekbones deteriorates as though eaten by acid, leaving thin layers of hide that enhance its skeletal appearance. A black dragon's head is marked by spikes and horns. Its tongue is flat with a forked tip, drooling slime whose acidic scent adds to the dragon's reek of rotting vegetation and foul water.
When it hatches, a black dragon has glossy black scale. As it ages, its scales become thicker and duller, helping it blend in to the marshes and blasted ruins that are its home.
Brutal and Cruel. All chromatic dragons are evil, but black dragons stand apart for their sadistic nature. A black dragon lives to watch its prey beg for mercy, and will often offer the illusion of respite or escape before finishing off its enemies. A black dragon strikes at its weakest enemies first, ensuring a quick and brutal victory, which bolsters its ego as it terrifies its remaining foes. On the verge of defeat, a black dragon does anything it can to save itself, but it accepts death before allowing any other creature to claim mastery over it.
Foes and Servants. Black dragons hate and fear other dragons. They spy on draconic rivals from afar, looking for opportunities to slay weaker dragons and avoid stronger ones. If a stronger dragon threatens it, a black dragon abandons its lair and seeks out new territory. Evil lizardfolk venerate and serve black dragons, raiding humanoid settlements for treasure and food to give as tribute and building crude draconic effigies along the borders of their dragon master's domain.
A black dragon's malevolent influence might also cause the spontaneous creation of evil shambling mounds that seek out and slay good creatures approaching the dragon's lair.
Kobolds infest the lairs of many black dragons like vermin. They become as cruel as their dark masters, often torturing and weakening captives with centipede bites and scorpion stings before delivering them to sate the dragon's hunger.
Wealth of the Ancients. Black dragons hoard the treasures and magic items of crumbled empires and conquered kingdoms to remind themselves of their greatness. The more civilizations a dragon outlasts, the more entitled it feels to claim the wealth of current civilizations for itself. A Black Dragon's Lair. Black dragons dwell in swamps on the frayed edges of civilization. A black dragon's lair is a dismal cave, grotto, or ruin that is at least partially flooded, providing pools where the dragon rests, and where its victims can ferment. The lair is littered with the acid-pitted bones of previous victims and the fly-ridden carcasses of fresh kills, watched over by crumbling statues. Centipedes, scorpions, and snakes infest the lair, which is filled with the stench of death and decay.

Basic Information

Anatomy

Black dragons appeared abnormally slender in comparison to other chromatic dragons—wiry, but not gaunt. Physically, they were most distinguished by their horns, which protruded from the sides of their heads and wrapped around, projecting forward. A large frill adorned the upper part of the neck. They smelled like rotting vegetation and foul water.

A black dragon grew up to a maximum size of 16 feet (4.9 meters) tall, 85 feet (26 meters) in length, with a wingspan of 80 feet (24 meters). They weighed up to 160,000 pounds (73,000 kilograms).

Genetics and Reproduction

Female dragons took the lead when it came to breeding, choosing their mate largely based on the size of the hoard of prospective males. Because of this, male black dragons would often brag about their accumulated wealth to communicative creatures or others of their own kind, in the hopes that rumors of their hoard would spread to any females in the area that were looking to mate. When two or more females selected the same male as their partner, they would fight for dominance high in the air above the lair of the male, allowing him to gaze upon his future mate's victory in admiration.
Black dragons were not noted as good parents, relying more upon disguise and hiding to protect their eggs than upon guarding them personally. Black dragon eggs must be submerged in strong acid while growing, which helped protect the dragon as well. Black dragons would only protect their young so long as that responsibility didn't threaten their own life. If they had to choose between saving their own life or those of their clutch or spawn, they would most certainly choose the former; though they would assuredly seek revenge afterwards.

Ecology and Habitats

Lair

Black dragons lived in swamps, jungles and fetid marshlands. They were cunning creatures who lived to inspire fear and rule by intimidation. The black, glossy scales of black dragons added to their camouflage within swamp lands. They preferred to ambush their targets, using darkness or water as their cover. They were excellent swimmers and often made their lairs in submerged caves or underground chambers near swamps or murky ponds. Their lairs always had two entrances: one underwater through the adjacent swamp or pond, and one above-ground, disguised amidst the undergrowth.
