1 A.S. - The Fall of the Ssthessic Vrasa
The empire of the yuan-ti, the Ssthessic Vrasa, was toppled with the siege and destruction of Tol Mannic. Though it took decades for the Ssthessic to be completely eliminated in what would later be considered to be a war of genocide, this was the end of the empire, and the beginning of the Kingdom of Endon's history.
102 A.S. - The Empire of the Sunderking
A powerful warlock and warrior, the Sunderking's war against the Ssthessic Vrasa consumed him, and he became more and more obsessed with the protection of his people and the destruction of everything else. In 102A.S., this was formalised, with the construction of the palace in Endon and the announcement of the expansion of his empire, the Immortal Throne.
183 A.S. – Sunderking is Overthrown
His death triggers the Sundering—an empire-wide revolution spanning decades—which fractures the realm into dozens of independent human-led fiefdoms. Many of these fiefdoms arise from former provincial strongholds or liberated rebel territories, each with their own claims to legitimacy. Early rivalries and shifting alliances form a tangled web of intrigue, setting the tone for Endon's future aristocratic politics. Though the yuan-ti are driven into exile or underground, their lingering cults and cursed ruins still haunt the land.
Major Fiefdoms Established: Astoll, Chantall, Dedeyrie, Fennelocke, Fenneray, Fireboste, Grenmont, Lanlodd, Manniq, Mendore, Nassine, Santal, Southendium, Tallow, Tarendium, Tor Gilane, Trannig, Virhurst.
212 A.S. – The Bastion Wars Begin
With no unified military authority, several fiefdoms fall into a cycle of conflict known as the Bastion Wars, named for the crumbling forts left behind by the Ssthessic. These wars see the rise of mercenary companies, proto-knightly orders, and shifting territorial claims. The Wars also result in the first major standardization of coinage and measurement among the fiefdoms that would later become Artaerys.
269 A.S. – Founding of Artaerys
King Eldoliere of House Branneth unites several fiefdoms around what is now Billingston to form the Kingdom of Artaerys. Distinguished by its centralized bureaucracy and early experiment with a royal charter, Artaerys becomes a dominant force in the Valley of Endon. With strongholds in key river crossings and fertile plains, it offers stability in exchange for military service and taxation. Artaerys' rise helps curb the constant warfare, and it becomes the first post-Sundering realm to be formally recognized by multiple factions as a “kingdom.”
295 A.S. – The Starfall Concord
A comet sighted over Endon's southern skies is interpreted by several cults and seers as a sign of divine will. This leads to the Starfall Concord—a loose agreement among several smaller states to observe a month-long truce during celestial events. Though symbolic, the Concord marks the beginning of religious diplomacy in the region and foreshadows the rise of faith-based kingdoms.
It is also noted as the origin of the Cult of the Henge, who believed that the comet was a significant event in the opening of the Iron Henge.
308–311 A.S. – The War of the Peaks
The eruption of the Smoking Mount above Guin-en-Falath the Greenlit Seas, forcing the Kolbar clans to migrate. When scouts discover rich veins of silver and iron in the Iron Mountains, the dwarves begin settling there. Southern human fiefdoms, fearing loss of mineral control, form a military alliance to repel the newcomers. After several bloody campaigns and sieges, a hard-won treaty is forged, granting the dwarves specific mining rights. In exchange, the dwarves construct enduring stone roads and pledge military aid. The conflict establishes the dwarves as permanent players in regional politics and allies to several human realms.
312 A.S. - The Battle of the Risen Sun
King Eldoliere, now an older man, repels a force of orcish raiders on the western border of Artaerys as they cross the Iron Mountains into the valley. He is killed, but the invading force is repelled.
338 A.S. – The Oakhold Crown
Following the Battle of the Byddervein—a decisive skirmish against northern raiders—the fiefdoms of Grenmont, Santal, Southendium, and Trannig form a lasting political and economic bloc known as the Oakhold Confederacy. A ceremonial overking is crowned in Endon, symbolizing unity, though true power remains distributed among the four High Seats. The Oakhold Crown institutes shared tariffs, border patrols, and a form of legislative democracy called the Suttmala.
390 A.S. – The Silent Plague
A mysterious illness spreads through river towns, killing thousands and destabilizing food supplies. Referred to as the Silent Plague due to its lack of visible symptoms before sudden death, the illness is believed to have originated from excavated yuan-ti ruins. In response, several fiefdoms ban further exploration of Ssthessic sites, inadvertently preserving their arcane secrets for future generations.
482 A.S. - Hiadittr's Castle Abandoned
For unknown reasons, the castle in the Greenmounts above Southendia is abandoned overnight -- all trace of the inhabitants disappears. The incident causes panic amongst the other kingdoms and fiefdoms in the valley, as no clear cause can be ascertained.
486-488 A.S. – The War of Thorns
A brutal and deeply symbolic conflict between the emergent Oakhold Confederacy and the northern duchies of Dedeyrie and Fennelocke, ignited by a border dispute over the Deadwood Vale. What began as a series of raids and retaliatory strikes escalated into full-scale war after the burning of the Wealdspire Monastery, a neutral druidic haven, by Dedeyrie’s mercenaries.
Guerrilla tactics, scorched earth campaigns, and the widespread use of beast-companions and hedge-magic led to heavy casualties and a bitter stalemate. The war ended only when the Circle of the Feybolg intervened and brokered the Treaty of the Wilderwatch, compelling both sides to withdraw and leaving Deadwood Vale under their autonomous stewardship. Though the war resolved little politically, it was the origin of the Wilderwatch.
490 A.S. – Treaty Pacifica
After generations of sporadic conflict, the Treaty Pacifica is signed at Lodban. Delegates from Artaerys (now mostly reduced to its heartland), Oakhold, Dedeyrie, Fennelocke, and Chantall meet to form a mutual alliance. The treaty establishes trade corridors, pledges military aid, and lays out succession protocols for disputes. The document also formalizes the name "Endon" as a shared cultural and geographic identity, though the Kingdom is not yet fully formed.
502 A.S. – The University of Talbot Opens
A sprawling library and magical repository is founded in Talbot, named the Skyfall Archives. Created by a coalition of wizards and scholars, many of them exiled from more militant fiefdoms, the University becomes a beacon of learning. Their early records and maps play a major role in later unification efforts.
541 A.S. – Gros’lot Founded
Established as a fortified border town near the Trollmark Hills, Gros’lot begins as a waystation for traders and pilgrims. Over time it becomes a bustling hub of commerce, smuggling, and arcane experimentation. Its charter allows for a rare degree of local self-governance, attracting freethinkers and mercenary companies alike. Later, it is excavated fully, and its lease with the Kingdom continues.
557 A.S. – Endon’s Pass Constructed
Endon’s Pass, a massive stone gatehouse and roadwork project through the Iron Mountains, finishes with the construction of Castle Agdir. The pass links eastern territories with the core realms of Endon, opening up trade with distant fiefdoms and elven principalities. Guarded by a permanent garrison, it also becomes a symbol of unity and technological prowess.
611 A.S. – The Elfhunt Vale Annexed
The Elfhunt Vale, once an independent borderland known for its gold dust rivers, are peacefully annexed by Endon after a series of marriages and trade accords. Their inclusion provides the Kingdom with the resources of the elves at Alaron, and begins a long tradition of intermarriage between the nobility of Alaron and the Royal Family of Endon.
711 A.S. – Battle of Fenlock
The last of the outlying principalities, the Kingdom of Virhurst (once Tarendium) declares war against Endon for hostile raids into the western marches and the Virhurst Forest. The decisive battle at Fenlock sees royal forces crush Virhurst. It is the first time a unified Endonian army is fielded and widely recognized as the true force of the Kingdom. The victory also enables greater centralization under the royal court, and adds Virhurst to the Kingdom.
783 A.S. – The Dagger Concord
Several assassination attempts on nobility prompt the founding of the Dagger Concord, a clandestine intelligence and counter-spy agency sworn to the Crown. The Concord becomes the model for later secret orders, but has to be suppressed and purged by the Crown in 841A.S when its leader aspires to the throne.
841A.S - The Iron Henge Incident
The Cult of the Henge, with a growing following in the south of the Kingdom, bands together and marches to the Iron Henge in an attempt to force the Henge to open a portal to another plane. The details of what happened are unknown, save that the Cult was defeated, and the watchtowers were built.
917 A.S. – Nonhuman Pogroms
A dark chapter in Endon's history, as fears of yuan-ti infiltration and foreign influence spark brutal purges. Nonhumans—especially halflings, gnomes, and tieflings—are exiled, imprisoned, or killed in mob violence and state-sanctioned roundups. The pogroms fracture diplomatic relations and drive many races underground or into hostile alliances. Dwarves and elves, with long memories, remain in their communities on the fringes of the Kingdom.
961 A.S. - The Giant of Whitehill Incident
The northern mine at Whitehill, a large iron and coal mine that also specialised as a gem cutting station, is closed when a local giant is angered by the miners. This marks another incident in a long and deteriorating history of conflict between the giants and the 'little folk'.
972 A.S. – Endon’s Pass Closed
Following a wave of banditry, plague, and secessionist agitation in the east, Endon’s Pass is closed. Trade slows to a crawl and the Kingdom becomes more insular. Many historians see this as the beginning of the kingdom’s stagnation before the Faramond Reforms.
981 A.S. – The Faramond Reforms
Queen Elanor I is deposed in a swift and largely bloodless coup by a cousin of the royal line, who became King Faramond I. Her reign, marked by indecision and lavish court expenses, was widely viewed as a low point in Endon’s royal legacy.
The new king, Faramond, is widely considered to be intelligent, charming, and a natural diplomat. He removes the outdated laws barring nonhumans, heavily taxes the nobility, and encourages trade between the Kingdom of Endon and other sovereign entities. He also canonises the ownership of the Crown over sites of archaeological significance, such as Sunderking's Barrow.
