Batiri
Chult is home to scores of independent goblin tribes collectively known as the Batiri. The Batiri worship Maglubiyet, a ruthless god of war. A Batiri tribe is ruled by a queen. When a queen dies, fighting ensues until a new queen emerges victorious and proclaims herself ruler of the tribe
While the Batiri have many cultural and mythical aspects that make them unique, they behave pretty much like other goblins; they are superstitious, cruel, suspicious of outsiders, clannish among themselves, and just as likely to torture and eat other humanoids as they are to trade with them --- and they are not only sadistic but highly creative in their torture.
Camp Vengeance
A handful of warriors from the Order of the Gauntlet escaped the undead onslaught against Camp Righteous by retreating towards the Soshenstar River. They ended their retreat by digging on the spot. Eventually they got word of their situation back to Port Nyanzaru, and they've since been reinforced. Their original, small base camp has been transformed into a fortified base far more capable of withstanding attack.
House of the Crocodile
In the early days of the world, Man stood by the banks of the river, frightened. Crocodile raised his head from the water and asked, "What troubles you, cousin Man?" Man replied, "I must cross this river, but I fear to enter the water alone, because it teems with your brethren." Crocodile replied, "It's true, you would not be safe. But I will carry you across the river safely on my back, if you promise to return the favor."
When they reached the far bank, Man asked, "How can I repay you?" and Crocodile replied, "I wish to see the realm of Humans, but I fear to go there alone, because it teems with your brethren. You must carry my on your back across your realm." Man had been tricked, but a promise is a promise, so he carried Crocodile safely on his back across the entire realm of humans, a journey that lasted many years. He also swore, in his anger, that never again would Men and Crocodiles be friends, and so it has remained to this day.
Mbala
The plateau of Mbala was once the seat of a small kingdom, but now only ruins remain. An old crone by the name of Nanny Pu'pu lives here, a wizened old woman who knows many things. Some say the crone worships death and knows many dark rituals. Most would rather not speak of her at all.
Merchant Princes
Seven merchant princes preside over Port Nyanzaru, each one with an equal vote in matters of state. Three of them male, four female. All are Chultan. Their single qualification is that they're the seven riches people in the city, with specific monopolies on all merchandise sold in the city.
The merchant princes surround themselves with loyal family members, and underlings, but they also employ foreign mercenaries both as city guards and as personal guards.
Port Nyanzaru
The fortified port at the south end of the Bay of Chult is known as "the Gateway of Chult". Since the destruction wrought by the Spellplague, no other city exists on Chult, along the coast or anywhere else, except ruins or overrun by monstrous creatures.
Until recently, Port Nyanzaru was under the firm control of Amn, a foreign nation. Nine years ago, Amn was forced to relinquish the city to a wealthy and powerful consortium of Chultan traders, or risk a bloody conflict that probably would have ended with the city winning its independence anyway. The Chultan traders have since grown into influential merchant princes, enticing folk from up and down the Sword Coast with their exotic wares.
Port Nyanzaru is a bastion of civilization and commerce in a savage land. The amount of business that unfolds here and the cash that moves through its counting houses would make any merchant of Baldur's Gate and Waterdeep jealous.
Enemies surround Port Nyanzaru on all sides. The jungle teems with ferocious reptiles and murderous undead, pirates prowl the surrounding sea, and the mouth of the bay is home to a greedy dragon turtle.
Soshenstar River
The Soshenstar flows north from the Aldani Basin to the Bay of Chult, tumbling down waterfalls every ten to fifteen miles. Outside of Port Nyanzary, the Soshenstar River is the best-known geographical feature on Chult, thanks to the presence of the Order of the Gauntlet and Camp Righteous and then Camp Vengeance. Many canoe flotillas ferried supplies and personnel up and down this river before Camp Righteous was destroyed.
Ubtao
A central figure in Chult's culture is the greater god Ubtao, who long protected the land and Chultan civilizations. But Ubtao grew angry over his worshiper’s endless warring and their reliance on him to solve all their problems. More than a century ago, Ubtao simply abandoned Chult, and his influence hasn't been felt there since this day. When he Lleft, the Chultans suffered crippling spiritual blow, but eventually the disunited, warring tribes learned to put aside their petty conflicts and unite as one people. To this day, the dinosaurs of Chult are revered as Ubtao's sacred children by many Chultans, even though Ubtao himself is no longer worshipped.
