Physically, they are of medium height and have a relatively strong physique, with a height range between 5 and 5.5 feet and a weight that can reach a hundredweight for males, while it's about half for females. Their forearms are much longer and stronger than their hind limbs and can even reach their ankles. Once they reach maturity, males develop characteristic fleshy and wide cheeks, called flanges; furthermore, adult males also have a throat sac that amplifies their voice. They have very long reddish hair on their shoulders, which forms a kind of waterproof coat. Their legs are short and weak with wide and flat feet with very long prehensile toes.

The Orangutan people, in ancient times, before the birth of the great Iwara empire, were scattered throughout the territory with many small regional kingdoms called mahajanapadas. Mahajanapadas were the sixteen to twenty most powerful kingdoms and republics of the Orangutan people, found mainly throughout the great Sillipon jungle. A little more than a century before the Tale, a military general overthrew the maharajah and took his place. Under his leadership, the little kingdom extended its dominion over a large part of the southern peninsula. Some dynasties and wars after this, the Iwara kingdom was formed (barely during the Tale), thanks also to the astute use of Tiger mercenaries in war to conquer neighboring peoples' territories.
A figure of great relevance in the Orangutan people's culture is the maharajah or rajà. Besides being the main ruler of a kingdom (or, subsequently, of a region), he is appointed to celebrate the rajāsūya: a recurrent consecration rite of the sovereign in which, among other things, he is reminded that "even if he had become the most powerful king and his rise unstoppable, Thialon, deity of conquest, is always watchful and his excellence must be pleased."

An important aspect of Orangutans' culture, in addition to their thriving fictional and spiritual literature and developed agricultural techniques, is their widely common architectural skill. The Orangutan people, in fact, tend to distinguish buildings into two specific types: day dwellings, or rather community buildings placed on the ground and built in finely chiseled stone; and night dwellings, or rather personal houses of single citizens, built in wood and bamboo on the tops of large trees. Only when a young adult has learned how to properly build his own night dwelling will he be granted the right to leave his parents' home and be recognized as an adult and useful member of society.
