Greiltish

Greiltish also called the Forbidden Jungle, is the catch-all term given to the wild interior of central and northwestern Tesslutut. Greiltish also extends southwards running up to the mountains of the Wastes of Re-Dover

Geography

The Principality of Greilthish is bordered to its Northlands by a portion of  Blachena and the Shtraphy of Whelra:. Directly to the North is the Dorgonie Bay . To its northwest is the nation of Bla-Ka-Kun and to its east starts the desert of Re-Dover which makes the border for the Wastes of Re-Dover. Traveling south around the desert shifts into the mountains of re-dover. The balṭānumma mountains are to the east of Grilthish and are the border of the Shtraphy of Whelra:
The region is dominated by a large forests of massive trees and rivers that flow north and drain into the Dorgonie Bay —mightiest of which is the Vanji River—and the Greilthish Jungle which surrounds them. However, there are two other jungles—the Kaavu Lands in the southwest, and the Screaming Jungle in the southeast. The are two other major lakes are Terwa Lake and the Lake of Vanished Armies.
The Barrier Wall mountains mark the southern border, Isītu Mountains lie on the eastern border. The Kho-Rarne Pass links the region with Wastes of Re-Dover , while the Ndele Gap leads into Shtraphy of Whelra:. The Isitu Range to raid Alkenstar, but following the highly successful raid of 4690 AR, the forces of Alkenstar collapsed the tunnels. The other significant highland regions are the Terwa Uplands and the Bandu Hills.

Nations

Countless nations and city-states can be found within the Greithish and its expanse, the most famous of which are listed here. Many more exist, some of which have been out of contact with the other lands of the Expanse, let alone those of the inner regions, for centuries. The nations of Greilthish are concentrated in powerful and independent city-states that have developed their own culture independent from their neighbors.
Bloodcove, a rough mercantile port and haven for Pirates. Jaha, ancient city of mysteries and astronomers. Kibwe, city of merchants and ancient statues near the Shattered Range. Mzali, a metropolis ruled by the undead god-king Walkena. Nantambu, the colorful city-state that houses the Magaambya university. Osibu, the secretive city that guards the Nemesis Well. Senghor, a coastal city and major naval power. Usaro, the horrific bastion of Angazhan's worship. Vidrian, a young nation having broken away from Chelish rule.

Foreign relations

Due to the absence of a centralized government, the diverse cultures and cities within Greiltish exhibit a wide range of relationships with foreign nations and among themselves. In Nantambu and Kibwe, peaceful foreign traders are warmly received, irrespective of their origin. However, in Mzali, non-Mwangi traders are subjected to severe consequences, including execution or even worse punishments. Coastal nations like Vidrian harbor deep animosity towards both Cheliax, which seeks to reclaim its former colony, and the Free Captains of the Shackles, as Vidrian no longer pays for their protection.

Economy

The forested landscape. Greiltish is a region abundant in valuable natural resources. Its fertile soil sustains lush forests, bountiful crops, and a wealth of rare herbs and medicinal plants. Additionally, the mountains within the Expanse yield copious amounts of ore and precious gems. However, this abundance has become a double-edged sword in recent centuries, as the local inhabitants find themselves compelled to defend their lands against militant colonists from Avistan.
Trade with northern nations primarily concentrates along the Expanse's western coast, where bustling ports like Senghor serve as crucial hubs for trading vessels arriving from various other parts of the Inner Sea region. Inland, the city of Kibwe plays a vital role in catering to overland trade caravans originating from the eastern Garundi nations, while Nantambu attracts esteemed scholars from all corners of the globe.
While the Expanse engages in significant trade with foreign entities, the settlements within its borders remain largely self-sufficient. These communities rely on local trade networks, exchanging goods and resources with neighboring settlements, and have minimal dependence on foreign imports. This characteristic frustrates northern companies such as the Aspis Consortium, as it limits their ability to exert control and manipulate trade within the region. Foreigners (most notably the Aspis Consortium) travel into the Expanse in search of treasure. The usual hazards of jungle exploration are made worse by the existence of evil spirits, sentient plants, and juju cults but legends of lost cities of gold and incredible riches continue to attract visitors. Wealth has been found in the region, and the existence of heavily-laden treasure ships heading north to Avistan from Bloodcove, Senghor, and also Anthusis (in Vidrian, formerly called Eleder) has encouraged the growth of the pirates of the Shackles to prey upon them.

History (needs to be edited)

Little is known today of the region's most ancient history, but the landscape is dotted with human ruins as old as almost any to be found elsewhere in Tesslutut.
Age of Serpents
Age of Legend In the Age of Legend, Mualijae elves began settling the northern Greiltish Jungle and came into conflict with expansionist humans, cementing the Greiltish's reputation as a dangerous place for humans. When Azlant rose, it came into conflict with the serpentfolk, and emerged victorious when the hero Savith decapitated the serpentfolk's patron deity Ydersius in the depths of the city of Ilmurea. In the aftermath of this massive victory the serpentfolk were forced from the world above, retreating into the depths of the Darklands. The Azlanti established an outpost of Saventh-Yhi but otherwise made no effort to settle the Mwangi Expanse. In this power vacuum a new empire rose, the Ghol-Gan. The Ghol-Gan began as a collection of small cyclops settlements united by their worship of nature and the sun and moon before spreading across parts of Greiltish, in particular the Sodden Lands. As the Ghol-Gani drove the remnants of the serpentfolk further underground they began to adopt some of their foul gods and tainted religious practices. By the end of the Age of Legend the Ghol-Gan were already well on their way to degenerating to the blood thirsty cannibals they are remembered as today.
Age of Darkness
The Ekujae rose from darkness to defend the Expanse from all threats demonic and draconic. In -5293 AR, the Starstone fell, leading to the fall of both Ghol-Gan and the city of Saventh-Yhi. The arboreal Dimari-Diji awakened just in time to observe this destruction, and while exploring the Expanses' benighted forests, he discovered the Nemesis Well. Dimari-Diji took it upon himself to protect Golarion from those who would abuse this inter-planar artifact, but he would not stand alone in this task. To the south the Zenj people of the savanna suffered greatly under droughts caused by Earthfall. Led by the pair of sisters Jahar, a healer, and Kamar, a druid their clan headed north into the jungles where they encountered Dimari-Diji. All three came to an agreement, founding the secret city of Osibu to protect the Nemesis Well in perpetuity.16
While many elves fled Golarion to Sovyrian on the planet Castrovel, the Mualijae elves remained behind.16 In the aftermath of Earthfall, the draconic deity Dahak slipped into the Universe via the aiudaras known as Alseta's Ring and devastated the Mwangi Expanse. Dahak's rampage was eventually stopped by the the Mualijae. At a great cost of lives, the elves managed to trap Dahak's manifestation between the planes, with the clans that would become the Ekujae sacrificing their greatest warriors to bind him there. After this binding the Mualijae began to splinter into the various tribes known today. With the discovery of the already ancient, demon-worshiping elven city of Nagisa some clans relocated there, dedicating themselves to studying and safeguarding the ruins, they became the Alijae. Other clans, fearing that Nagisa's demonic influence would corrupt them, fled to the shores of Lake Ocota where eventual conflict with the first Gorilla King would forge them into the Kallijae. The dwarves also first arrived in the Mwangi Expanse during the Age of Darkness, building their ancient Sky Citadels of Cloudspire and Dongun Hold that still endure to this day.18
Age of Anguish As the Age of Darkness passed into the Age of Anguish, the legendary heroes Old-Mage Jatembe and the Ten Magic Warriors did their best to re-establish civilization. They defeated the sorcerous King of Biting Ants at the Doorway to the Red Star, and established the wizardly academy of Magaambya in Nantambu.5
Age of Destiny In -2556 AR, as the Age of Anguish gave way to the Age of Destiny, followers of the Magic Warrior Black Heron united some Mwangi tribes to fight the cult of Rovagug. After the cults are defeated, they founded the Shory Empire, whose first flying city Kho took flight in -2323 AR. The Shory's flying cities maintained a nomadic lifestyle, offering knowledge and services to cities they passed over. As they began consorting with daemons and entities from the Dark Tapestry, the Shory began to decline, until Kho fell in -632 AR and Ulduvai followed in -507 AR.195
Age of Lost Omens In 4138 AR, Cheliax established the colony of Sargava on the western coast. The success of the colony was seriously curtailed by the appearance of the Eye of Abendego upon Aroden's death in 4606 AR. When Abrogail Thrune I ascended to the throne of Cheliax in 4640 AR, Baron Grallus, who had backed a rival of House Thrune, declared Sargava's independence.20
The city of Usaro, on the southern shore of Lake Ocota, is home to bloodthirsty apes and charau-ka who revere Angazhan. Until recently led by the Gorilla King, they long ensured that the heart of the Mwangi Expanse would threaten the lives of others.215
The unification of the pirates of the Shackles in 4674 AR22 had adverse implications for the passage of goods to and from the Expanse, although it was the pirates themselves who established the free port of Bloodcove, through which much of the region's riches now pass en route to Avistan.23
In 4715 AR, the anti-colonial resistance in Sargava succeeded, overthrowing the government and establishing the new nation of Vidrian.

Inhabitants

The lush and vibrant Mwangi Expanse brims with legends, stories, and rumors that evoke both awe-inspiring and cautionary tales. Despite its abundant treasures, the inhabitants of the Expanse remain relatively unknown to those outside the Inner Sea region. Within this land of natural splendor, artistry and intellectual pursuits flourish, as its resilient inhabitants labor diligently and employ clever tactics to prosper in an environment that frequently poses threats.10
The Expanse serves as a meeting ground for various cultures, where diverse peoples not only coexist but also thrive amidst the numerous perils that accompany this bountiful territory. The Mwangi region abounds with such abundance and wealth of resources that hunger and scarcity are rare occurrences. The ready availability of sustenance, water, natural fibers, and valuable materials facilitated the early Mwangi inhabitants in establishing self-sufficient communities, cities, and even independent nations, shielded from external influences and disconnected from the wider world.
The most populous heritages of peoples found in the Mwangi Expanse include elves and halflings, in addition to humans of Garundi, Mwangi, and Taldan extraction.25 Kholo of the Expanse also have their own unique society.26

Languages

The most-commonly spoken languages in Greilthish include Taldane, Elven, Garundi, Halfling, and the Common language of the region

Tribes and societies

Some of the societies of the region are as follows:
Dwarves There are two main groups of dwarves in Greiltish, with virtually no contact between them: the Mbe'ke, who migrated to the Terwa Uplands and founded the Sky Citadel of Cloudspire in -4372 AR, soon after the Quest for Sky; and the Taralu, who live in scattered clans across the eastern Greiltish Jungle.
Elves Unlike most elves of Avistan, the elves of the Mwangi Expanse did not relocate to Sovyrian or retreat underground during Earthfall. Instead, these tribes, collectively known as Mualijae, continued to live as they always had.
The Mualijae are descendants of elven explorers who established a nation spanning most of the Greiltish Jungle in the Age of Legend. After Earthfall, the Mualijae stopped Dahak's rampage through the Greiltish Expanse at a great cost of lives, and some claim that the modern tribes were left behind in order to fight the Great Darkness (as Dahak becomes later known as) when it returns. The epic poetry inscribed in Elven on the walls of the ruined city of Nagisa is the sole known non-oral depiction of this legend. After defeating Dahak, the Mualijae split into three groups: the Ekujae, who stayed around Alseta's Ring; the Alijae, who settled near Nagisa in -5014 AR; and the Kallijae, who fled Nagisa in fear of being corrupted, and subsequently settled near Lake Ocota.
Lizardfolk The Mist Dragons are secretive lizardfolk who live and travel exclusively in rain-forest treetops of the Expanse.
