The World of Greyhawk Timeline is a list of fictional historical events that either explain the history leading up to the present state of the World of Greyhawk/ Dungeons & Dragons campaign setting, or that enumerate further developments described in campaign products published by either TSR Inc. or Wizards of the Coast.

Development of the original timeline

The original campaign setting of Greyhawk was a home campaign world invented by Gary Gygax in 1972 while playtesting the game that would become Dungeons & Dragons. In the beginning, the entire "world" consisted of a single dungeon underneath an abandoned castle. This world eventually grew to encompass a nearby city and then some neighboring states, but since Gygax, and eventually his co-DM Rob Kuntz were making up the story as they went, there was no need for an elaborate historical background. Although Gygax referred to Greyhawk in many of his columns, magazine articles and D&D adventures, the overall world remained his personal home campaign for several years.

In 1979, Gygax made the decision to publish the world of Greyhawk, but in order to do so, he made substantial changes to his home campaign world. Rather than using his own map, which was simply a map of the United States overwritten with his cities, towns and regions, he sketched out a new world called Oerth, then concentrated on one corner of one continent, a place called the Flanaess. In order to quickly explain the current state of the world, and the motivations of various states and important characters, Gygax delineated twenty-one historical events that bracketed a thousand years of "pre-history" leading up to the "present" time of 576 CY (Greyhawk/Common Year Reckoning). Gygax resisted the urge to fully outline a detailed timeline in order to give players as much leeway as possible when designing their own home campaigns: "The history is given briefly, and most states are only outlined generally so as to allow as much personal input as possible from DMs who decide to acquire and use it."

For the next few years, Gygax was the arbiter of all events that occurred in Greyhawk until he was ousted from TSR in 1985. TSR took over creation of new events for his world, and a re-visioning of the campaign in 1992 resulted in an extension of the end of the timeline from 576 CY to 585 CY. In 1996, Wizards of the Coast bought TSR, and several years later, again reset the campaign, resulting in a further extension of the timeline to 591 CY. From 1985 to 2003, newly published material added more "backstory" to the Greyhawk history, subsequently adding many items to Gygax's original timeline.

Historical Ages

The following terms are sometimes used to describe eras in the history of eastern Oerik: Sages divide history into five eras.

Constituting the early history of the multiverse, when the forces of Law battled primal Chaos. These three eras together are called the Age before Ages.

In the First Age, the multiverse came into being and beings of law and chaos, good and evil warred for millions of years.
In the Second Age, the Material Plane was formed and the first gods came into being.
In the Third Age, the aquatic aboleth race was created by divine accident, the aboleth went on to master magic and create many creatures including the first humanoids. This Age culminated in a massive battle between Law and Chaos, crippling the ancient powers.

The Age before Ages concluded at the Battle of Pesh, a colossal battle between law and chaos. On the side of Law were the Wind Dukes of Aaqa, an air elemental race whose empire spanned many worlds, while Chaos included demons and evil elder elementals led by an obyrith called the Queen of Chaos. The result was a stalemate: the Wind Dukes destroyed or banished the most powerful demons, but lost too many of their number to continue the battle of law against chaos.

In the following Age, humans and other species became numerous and human civilization began. This is the current era, and is predicted to end one day with the Age of Worms, where all life will be destroyed.

Age of Mortals

The first mortal was created by accident when Piscaethces, a massive Far Realm creature perhaps related to the Sleeping Ones, brushed against the prime material plane, creating the first monstrous aquatic aboleth. As they have perfect genetic memory, all aboleths remember this event.

Over millions of years the aboleths came to dominate the material plane, learning the first magic and creating creatures – the oozes, at first, and later the first humanoids, which they created as slaves. Precisely who created what race is unclear, but the gods found that mortal faith increased their power. In exchange, they freed the humanoids from aboleth control.

The mortals were also valuable to the primordial creatures for their souls, which the baernaloths used to build into the evil yugoloths, and the obyriths to create the first demons, the first demon, Demogorgon, was forged from the primal fears of the first mortal souls. The Demons grew numerous, and overthrew most of the obyriths before turning against Asmodeus’ devils, whose numbers included deities’ servants turned traitor for the promise of power.

Age of Men

Distinct from the Age of Mortals by the ascension of the Races of Men (in this context, being all humankind and demihumans), rather than just the birth of the races.

With the primordials weakened and the gods reinforced by exponentially increasing numbers of mortal worshippers, the era of humanoids and their chosen deities began.

In the millennia after the Battle of Pesh, humans and the other races created civilization and learned the use of magic. The demons and devils continue to fight each other in what has become termed the Blood War, although few are ancient enough to remember why it started. The Wind Dukes never recovered their losses.

Also called the Waiting Age: a time of death, decay, and writhing doom that lurks in the shadows of every tomorrow. Doomsayers speak of the end times, an era of destruction known as the Age of Worms. Servants of mad cults work to hurry this along. Neither the deities nor the remaining primordial evils want this to happen any time soon, since both benefit from the continuing growth of the human race.

The Greyhawk timeline

c. -14,010 CY Sometime before this point in time the city that will one day be called Exag is abandoned by the race of Crafters. (DNG#145 "Exag, City of Clay" p. 49)

c. -14,000 CY Valley elves present in the Valley of the Mage.

c. -13000 CY The founding of the kopru city-state Shotho'Kopur. The kopru calendar begins. (Dragon #354)

c. -7411 CY The Torhoon empire extant in Hepmonaland. (Dungeon #77)

c. -7408 CY The Doomgrinder is created. (The Doomgrinder 2)

-6416 CY The first of a group of traveling Grey Elves, exploring the South Central portion of Oerth meet with tribal leaders of the Se-Ul (People of Ul). They strike up a friendship and the elves began tutoring the humans in mathematics, language, art and non-clerical magic.

The Se-Ul proved apt students and soon were constructing cities and delighted the elves both with their creativity and their productivity. The cities of the Se-Ul were patterned similar to those of the Grey Elves set mountain fastness, but these occupied the plains and river deltas of the southlands.

-6233 CY A group of beautiful dark skinned humans called Kersi from over the southern sea from a large island continent they called AnaKeri arrived on the southern portion of the Flanaess in large wooden platformed outriggers.

-6067 CY The Se-Ul began systematized trading with the tribes to the north and east. The Baklun in the northern plains and the Flan who dwelt just west of the mountains were among these. Sea trade routes to AnaKeri are developed. The 10 cities of the Se-Ul develop into separate city states, but all are ruled by a single council of lords under the watchful eye of the Grey Elves.

-5775 CY The Gray Elves depart from the Se-Ul. News of a fierce war between the Grey Elves and their dark kindred in the East spreads, much like the fire which mysteriously begins to belch from the mountains in the East. The Mountains, once the place of the Grey Elven cities, are renamed The Mountains of Fire, and the Mountains of Hell, although the Barrier Peaks and Crystalmists remain calm.

-5739 CY Relations between the Se-Ul city states, deteriorate. The last council of the cities is held. Each city arms itself against the other.

-5710 CY After many years of fighting, one city state, ReAtryniBa, slowly brings the others under control. It’s Lord, Anainyer, slowly begins to re-establish the trade which has been damaged by years of war.

-5703 CY Anainyer defeats, BiTharOl, the last Se-Ul city to hold out against him. He proclaims himself “The First Protector of the Se-Ul.” He renames ReAtryniBa, Suela, the city of the Suloise.

-5531 CY After a series of strong “First Protectors” and the development of the interior lands, First Protector Alianor-b-Hurn turns his eyes outward, and desires more control of the trade goods. He first attacks the settlements of the Kersi to the south, and proclaims their lands forfeit to the Suel peoples. He then begins planning “The great invasion” of AnaKeri.

-5518 CY Alianor with a large naval force attempts to invade AnaKeri. As the massive armada approaches, the outriggers of the AnaKeri are no match for the mighty warships of the Suel. The Clerics of the AnaKeri awaiting certain doom, call on their deities for protection, and they are heard. The deities encircle the island continent with a maelstrom of wind and wild seas and the invading fleet is totally destroyed. Few straggling ships return, the only survivors to tell the tale. The wall of wind and water remains cutting the peoples AnaKeri off from others entirely.

-5515 CY During the years of the turmoil following the destruction of the Se-Ul fleet, Obendar, a mighty Suloise mage, rediscovers lost grey elven magics and creates the Great Binders and imprisons the genie king Ali Ben Yala. He then forces each of the genie princes of the North to swear obedience “as long as your king remains imprisoned.” He then crafts nine magical items to bind the king and his eight princes. The use of genii to empower the Se-Ul is considered to be the beginning of the Times of the Se-Ul and the year of Ali Ben Yala’s imprisonment is reckoned the first year of the Se-Ul.

-5442 CY The Genii Princes are forced to perform magic for the Suel magi.

-5424 CY The Suel appoint a Regency of three men to rule in place of the First Protector. This triumvirate divides the Suel realm into three districts and rules in an amazingly efficient manner. The building of ships for anything other than coastal or river travel is banned. No ship is allowed to sail beyond the sight of the Se-Ul lands.

-5166 CY The seventh Regency is appointed. Two of the Regents, immediately turn on the third and destroy him in the First Regent War, claiming that he is possessed by evil beings.

-5046 CY The tenth Regency is appointed. The great, great, great, great grandson of Alianor, Arinanin, approaches the Regency and demands that he be restored as First Protector. His request is denied and he is imprisoned.

-5026 CY Tilorop-b-Nan, the great, great grandson of the Regent deposed in the First Regent War, frees Arinanin-b-Korin from prison. He tells him that his family has secretly been worshipping a seldom whispered name, one called Tharizdun.

-5010 CY Arinanin and Tilorop mount a campaign against the Regency, but are defeated in the Second Regent War. Arinanin is destroyed, but Tilorop uses arcane energy to transform him into the first lich on Oerth.

-5007 CY Blight Wyndom Pryce travels from the future (589 CY) and attempts to destroy Tilorop. Blight is killed by Tilorop in the battle but the legend of the great bull of heaven does much to foster the worship of Hieroneous.

-5003 CY Tilorop and Arinanin mount an attack in the Third Regents War and overthrow the Regency Council. Tilorop is appointed Priest Regent and the lich, Arinanin, proclaims himself Chief Regent of the Se-Ul. The Time of Darkness begins.

-4666 CY The last of the Grey Elven cities in the mountains now known as the Crystalmist is discovered and destroyed by a concerted effort on the part of the Drow/Suloise and Giantkind. The defense of the city is so great however, that drowkind and giantkind are also nigh exterminated. The Suloise army which aided in the destruction of the elven city is destroyed to a man, and no word of them can be obtained. The remnants of the grey elves flee eastward to the interior of the eastern portion of the continent.

-4616 CY The chief houses of the Se-Ul rise up in unison and overthrow the Priest Regent, and drive Arinanin into the North. The priesthood of Tharizdun is likewise driven out. They flee northeastwards, and establish a temple somewhere in Southern Yatils. The Council of Noble Families is formed to rule the Se-Ul.

-4463 CY The four “Elven Realms of the East” are established, and a calendar is used for the first time among the elves to count their own days. Highfolk is established in the Northwest to guard the northern ways, Celene the Central Kingdom, Aliador in the Griff Mountains, and Arrisa in the Southeast Aerdi Sea (in what is now called the Spindrift Isles).

-4414 CY Elonzir-b-nar, the Prince of the house of Rhola (worshippers of Jascar and other Suloise deities of weal) is proclaimed the First Emperor of the Suel Empire.

-4403 CY The Wind Dukes of Aaqa, meet a gathered force of evil humanoids and drow on the Plains of Pesh (in what is now Keoland). This is the last recorded great battle between Elves and their drow cousins. The Dukes shatter the dark elven armies.

-4403 CY to -2253 CY Between these times the realms flourish, the battles with humanoids are frequent, but the might of each of the realms is unchallenged. This is known as “The Time of Flowering” and much of the best of Elvendom came to pass in these days. The 12 Gray Elven cities were built, including Erieadan, the High Seat of Elvendom and The City of Summer Stars. Many mighty magics, and songs and items of beauty were crafted. The history of this time is largely hidden from humans, however, because there were few (if any) humans in the East at this time. Elves rarely speak of it today. Among the few known personages to have lived during this time were Queen Ehlissa and the Elven Minstrel Ye’Cind.

c. -4358 CY The Tiamat-worshipping Ur-Flan civilization of Caerdiralor rises on the Dragonshead Peninsula. They engage in a war of extermination with the dwarves and gnomes of the Headlands. [1]

c. -4217 CY Caerdiralor's capital, Myrsyrna is devastated in a sudden catastrophe. The surviving elite flee across the Sea of Gearnat, landing on the coast of the grasslands that are now the Bright Desert. Unable to escape through the Abbor Alz and hunted by the native nomadic Flan horse tribes, the refugees are driven into hiding. [2]

-3756 CY Many nomad families of the northern plains first encounter the Suloise Empire. They began to rely on trade with the empire. Herd animals, horses, cloth, and pottery are exchanged for superior weapons and adornments of “civilization.”

-2313 CY to -2312 CY Zofar ad-Zol proclaims that there is inherent evil in the binding of Genies and commands that all of the Great Binders be turned over to him for destruction and release of the genies. Zofar collects five of the Binders, in addition to the Binder of the King. Houses Fruztii, Cruski, and Schnai violently oppose this move, causing the Suloise War of Revolution

-2281 CY Zelfed ad-Zol, the son of Zofar, brings the war to an end but does not gain the remaining Binders.

-2269 CY The first recorded “Slavery Raid” occurs. Suloise forces capture an entire family of Bakluni and take them into the Suel Empire in servitude.

The years of Conquest and Prosperity begin. No major foe opposes the might of the empire of the Suloise, although they do not push eastward, because of some fear of the Elven hosts. Magic is rigorously pursued. Old Grey Elven texts are discovered and studied. The might and haughtiness of the Elves is copied in manner in the courts. But their wisdom is not… Slavery becomes common and widespread in the Suloise lands, this continues for many centuries. The Flanae in the southeast (just west of the Hellfurnaces), the Oerid to the east, the Kersi (the long distant descendants of those who first sailed from AnaKeri) to the south, and the Baklun to the north, and several unnamed small tribes to the west all fall under the grip of the Suloise fist. The entire of the western half of Oerik, is controlled by the Suel. But the drow and darker forces, and a fear of other elves, halt the eastern expansion. The Oerid are the most oppressed of all Suel subjects. It is believed that Suel priests have foreseen greatness in these people which rivals that of the Suloise

-2266 CY The Flanane, under the protection of Beory, Pelor and Rao flee their lands in mass, making a perilous crossing of the Hellfurnaces. They move North into the lands of Eastern Oerik, later called the Flanaess, as the first human inhabitants of the area. Initially, they are well received by the demi-humans dwelling there.

-2064 CY “The Great Betrayal.” After treating with seven nomadic merchant clans at a merchant gathering, the Suloise Odiafer, attacked the merchants, attempting to take their goods and enslave them. The families drew their trains together and fought to the last person instead of surrendering.

-2055 CY Suloise armies march into the northern plains and claim overlordship. The nomads are generally defeated when they resist. The first Suloise fortresses in the north are constructed. For the next 600 years the Bakluni are subjugated to the Suel.

c. -2004 CY The Flan people spread across the Flanaess. In what is now northwestern Perrenland, a Flan tribe led by a powerful warlord named Exag, fleeing a horde of hostile lizardfolk, stumble upon a city that was built by the Crafters. An old woman in the tribe, Prizin'ha, wins the day by sacrificing herself at the top of one of the Crafter pyramids, summoning an army of earth elementals that defeat the lizardfolk.

He discovered in the libraries a book from the Suel entitled “The Fate of Tilorop.” He secretly begins to worship Tharizdun.

-1733 CY Galitholian receives a warning from the mages and priests of Arrisa, his reply is “I am the High King of Elvendom, you would do well to remember that!”

-1711 CY Vecna erects a black tower in the middle of the Nyr Dyv. He claims chieftanship of his tribe, the Ur-Flanae and slays the former chieftain in combat by use of magic.

-1710 CY to -1683 CY Vecna shielded his presence from the Elves by use of magic. He studies “The Fate of Tilrop” and is driven by an insatiable lust to live as long as the elves. His established towns on the model of the Gray Elves, and began to experiment with his Ur- Flannae for the “Ultimate Solution to Death.” Several undead are created.

-1671 CY Vecna perfects the technique required for Lichdom. He transforms himself. He goes north to the plains and brings forth many humanoids to his banner. He corrupts and twists his people, and, through his breeding program, now has a host that far outnumbers the elves to the East.

-1669 CY to -1645 CY Vecna marches against Galitholian, bringing back his slaughtered soldiers as an undead hoard. Slowly his alliance of humanoids, undead, and Flannae drive the Gray Elves back to their mountain fastness.

Although they meet with initial success, Vecna calls on the powers of Tharizdun and unleashes a magical burning force which causes the Bright desert. Many perish and the elven host is thrown into a panic. They retreat to Celene, but Vecna does not advance. His eyes are fixed to the east.

-1545 CY The Bakluni, under one of their wandering chieftains, Ali-ben-Onar, unite in an effort to throw off the Suloise yoke. During the War of Seven Score Nights one of the Binders is captured. The war ceases when the Bakluni threaten to use this item. The Suloise cede a large portion of “their” Northern territories to the Bakluni.

-1540 CY “The First Victory” The Bakluni claim a large portion of the northern lands as their own by treaty with the Suel. The family Amirs and Sultans gather and elect Ali-ben-Onar, by proclamation, as “Caliph of All the Families of the Baklun”.

-1539 CY The Suel and Bakluni come to an uneasy peace. The House of Zolax plots to fight the Bakluni influences (in Bakluni lands, and on other groups such as the Oeridians) wherever found. The first of the Grey Elven mountain cities falls to Vecna’s armies. This is the beginning of the 400 Year War.

But once in the plains, Vecna revealed a new weapon, a black sword forged of material from the stars. Vecna met Gilthonial in single combat and slew him. The army of Vecna then destroyed the elven host, and marched into the mountains. They inhabited and defaced the elven cities, remaking them in the image of Vecna. Four cities, however, were never found. The capital, Erieadan, the height of Gray elven architecture and power, was destroyed to a stone. So ended the Elven Kingdom of Aliador, the seat of the High King.

Vecna’s body is destroyed. Despite this, the three remaining hidden Gray Elven cities of Aliador do not reveal themselves.
After this several small Flannae kingdoms arise, but none match the might of the Ur-Flannae under Vecna, several northern Flan fearing the both the wrath of the elves and the brutality of another lich-king flee their cities and turn back to a tribal systems of government.

The remnants of the Three Pursuing Houses (Schnai, Fruztii, Cruskii) are devastated and blasted by magic. Their mages minds are wiped of all magic, and the people are confused and terrified.

The ferocity and magical might of the movement scatters the Oeridians in it’s path, causing the remainder of the Oeridian to migrate, who in turn attack the beleaguered Flannae. One of the High Mages, Slerotin (called “the Last High Mage” by the rebellious Zolite Suel who settle in the south of the Flanaess, and the continent of Hepmon), causes a huge tunnel to be bored into the Crystalmists, through which the Zolite Suel flee.

The three pursuing houses, unable to find the magical tunnel, turn north, where they are met by regrouped Oeridians and fearful Flanae who harry and drive these Suel Houses south. Many are lost and remain in the Amedio Jungle. They eventually move back east and march toward what is now the Rift Canyon. (-442 to -423 CY)

-443 CY The First Division occurs. One of Zellifar’s minions, the High Priest Pellipardus, slips away from the Zolites and takes his minor family to the Ratik area, in the North.

In retaliation, Bakluni clerics and mages gathered at Tovrag Baragu, using the arcane powers of the Binders and drawing upon the energies of their holiest site, withstand these energies and counter strike with the Rain of Colorless Fire on the empire. The remains of this expenditure of energy are now called the Sea of Dust and the Dry Steppes.(Guide 9)

-419 CY Zellifar enters the Griff Mountains alone. None know where he goes or what he does there.

-417 CY The Three Houses of Pursuit move into the Thillonrian Peninsula. They remember and turn to deities which were basic and strong, Kord and Llerg, forgetting others in the face of the strong magics of Slerotin.
