At first glance, pterafolk in their natural forms looked like tail-less lizardfolk or saurials, but they were much taller and leaner and had elongated cranial crests like pteranodons. They had smooth, fine scales, much like those of a snake, that ranged in color from forest-green to light shades of tan. Their arms and legs were thin and long, and their hands and feet bore sharp claws.
While not all lizardfolk were evil, it was generally agreed that pterafolk were cruel and vicious as a rule. They were highly untrusting of anyone outside their own race. They had an innate predilection towards violent behavior, but those raised in other societies sometimes had the capacity to overcome this tendency and take on alignments beyond evil.
Pterafolk liked to collect things valued by the communities near where they lived.
Similar to how a yuan-ti could change its form at will into a snake, the pterafolk could "unfurl" a pair of eight-foot-long, leathery, webbed wings for flying or even take the form of a small pteranodon. They tended to only use such forms when they wanted to fly.
Pterafolk rarely strategized, but they had certain tactics they used regularly in combat. They used dive-bombing tactics, dropping from altitudes of 100 feet (30 meters) or more to swoop down on their foes and strike with their rear claws, toothed beak, or barbed spears. They preferred circling their opponents and diving upon them in turn such that there would be a constant stream of diving attacks from all directions.
Some clans cared little for training and relied only on instinct in battle. Others had a form of organized training that produced fighters, barbarians, or rangers. If they wore armor or used weapons—often barbed spears— they were custom-made to not interfere with flight.
Pterafolk were sometimes called the "Hidden Folk" along with ophidians, because they were not well-known and preferred to stay that way. While they were extremely rare outside the Chultan Peninsula, in 1372 DR they made up 4% of the population of Chult.
Pterafolk lived either in large tribes or in small bands of between ten and thirty individuals. The smaller groups were disorganized and generally controlled by which ever pterafolk individual was strongest or loudest.
Larger tribes had established communities with cultures similar to those of other races living around them. Tribes were subdivided into clans of related individuals. Strangely, these larger tribes were often ruled by a spirit naga, who functioned as chieftain with absolute power and responded to the tribe's requests and acted as a judge over their disputes.
Pterafolk distrusted magic, so spellcasters were very rare among them, and they would usually destroy any magical items they found as spoils. If the tribe was overseen by a spirit naga, it might train up acolytes who could cast divine magic.
After the breakup of the World Serpent, most pterafolk took to worshiping Shekinester, the goddess of spirit nagas. They held that the primary forces of nature were chaos and destruction. They followed their deity by bringing about more destruction into the world.
Pterafolk ate both meat and vegetables. Their favorite meats were from brontotheres and hornless rhinoceros—massive prehistoric mammals still roaming in the jungles of Chult—and axebeaks—mammoth flightless birds. They also consumed jungle fruits, roots, bark, and flowers.
Pterafolk mated for life. Females laid eggs high on mountain peaks and both parents guarded the eggs. When the young reached adulthood, they would leave the tribe and form smaller bands until they could establish territory or a tribe of their own.
It was exceptionally rare for a pterafolk individual to die of old age; death in battle was expected.
In fact, neither tale was true; pterafolk were one of the many creations of the sarrukh of Mhairshaulk and were bred from lizardfolk. The pterafolk gave the sarrukh armies more power, owing to their flight and viciousness, but they were also more difficult to control.
After the fall of Mhairshaulk, many of the sarrukh's enemies attempted to hunt down and destroy the pterafolk.
While they usually kept to themselves, in 1363 DR, Kaverin Ebonhand had managed to convince several dozen of them to fight with him in his assault on the holy city of Mezro. They dropped rocks and explosive items upon the city from the air. When Kaverin was slain by the famous Harper Artus Cimber, however, the pterafolk abandoned the fight.
