Biology and Physiology
Adult dragons are massive, reptilian creatures with powerful muscles, thick scales, and large wings that enable them to fly. Their size varies by type, but they can range from 30 to 60 feet in length. Their scales are incredibly tough, providing significant protection against physical and magical attacks.

Intelligence and Behavior
Dragons are highly intelligent beings, often possessing a cunning and wisdom that surpasses many other creatures. They are capable of complex thought, strategy, and even magic. Dragons can be both solitary and social, depending on their alignment and personal preferences. They often have vast territories which they fiercely protect.

Lairs and Hoards
Adult dragons are known for their elaborate lairs, which are often located in remote, difficult-to-access areas like high mountains, deep forests, or beneath the sea. These lairs are typically filled with treasure hoards accumulated over centuries, including gold, gems, magical artifacts, and rare items.

Breath Weapons
Each type of dragon has a unique breath weapon, such as fire, ice, acid, lightning, or poison. This ability is one of their most feared and powerful attacks, capable of devastating entire armies or incinerating foes in an instant.

Magical Abilities
In addition to their physical prowess, many adult dragons possess inherent magical abilities. These can include spellcasting, shape-shifting, and other supernatural powers. Their magic often reflects their elemental nature and can be used for both combat and utility purposes.

Cultural Impact
Dragons hold a significant place in the mythology and culture of many fantasy worlds. They are often revered as gods, feared as monsters, or respected as wise and ancient beings. Their influence can be seen in the folklore, religious practices, and societal structures of various civilizations.

Ecological Role
Dragons play a crucial role in their ecosystems, often acting as apex predators. Their presence can influence the behavior and population of other creatures within their territory. Some dragons may even form symbiotic relationships with other species, offering protection in exchange for services or tribute.

Alignment and Morality
The alignment of a dragon greatly influences its behavior and interactions with other creatures. Chromatic dragons (e.g., red, blue, green) are typically evil, while metallic dragons (e.g., gold, silver, bronze) are usually good. This moral dichotomy shapes their roles as either villains or allies in many stories.

Lifespan and Aging
Dragons have incredibly long lifespans, often living for thousands of years. As they age, they grow more powerful and wise, but also more set in their ways. The oldest dragons, known as ancient or great wyrms, are nearly god-like in their strength and knowledge.

These elements make adult dragons formidable and fascinating creatures within any fantasy world, capable of being both a mighty challenge and a source of rich lore and adventure.

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.
