A simplified view of the timeline

The following is a timeline of the Diablo series. Absolute dates are based on the numbering system of the Anno Kehjistani.

The Dawn[]

  • In the beginning, there is nothing, save a Pearl containing a dreaming, mighty, unfathomable spirit, the One, Anu.
  • At some point, Anu considers itself. Desiring perfection, it casts all evil from itself, creating the Prime Evil, Tathamet.
  • Now two separate beings, Anu and Tathamet war against each other within the Pearl for countless millennia, until finally exhausted from the battle, they both deliver their final blows. The resulting cataclysm destroys them both and lays the foundation for all Creation. Pandemonium marks the epicentre of this event.[1]

The Great Conflict[]

Main article: Great Conflict

  • Angels and demons wage war over the Worldstone, the artifact changing hands many times. The Pandemonium Fortress is built to house it, but it too changes hands many times.
  • After eons of battle, the angel Inarius seeks to abandon the Great Conflict. He gathers like-minded angels and demons, most notably Lilith. His renegades steal the Worldstone and use it to create their own realm where they will be free of the conflict—Sanctuary.
  • The Great Conflict grinds to a halt, as without the Worldstone, Heaven and Hell are left without a goal.[1]

The Creation of Sanctuary[]

  • After forming Sanctuary, Inarius and Lilith mate and create offspring called nephalem. Other renegade angels and demons do likewise. Thus are born those who would later be known as the Ancients, from whom all humans are distant descendants.
  • The renegade angels and demons fear the power of the nephalem and consider exterminating them all. Lilith is driven into a mad frenzy at this prospect of her children being exterminated, so kills every single renegade angel and demon in Sanctuary except for her once lover Inarius.
  • Inarius is horrified by Lilith's actions but can't bring himself to kill her, so banishes her from Sanctuary into the Void.
  • Inarius twists the powers of the Worldstone to weaken the powers of the nephalem over the next generations until no special powers remain. Thus emerges the race of humanity, which bears no knowledge of its birthright.[1]

The Birth of Civilization[]

  • Millennia pass and mankind begins to populate the world, giving rise to various civilizations.[1]

c. -2300[]

  • Recovered artifacts indicate that by this time, writing, art, and science had become an integral part of human culture. Modern scholars agree that this time marks the beginning of Kehjan, humanity's first civilization.[2]

c. -2200[]

  • The cultures of Kehjan formalize the study of magic. This leads to the formation and growth of the Mage Clans.[2]

c. -2100[]

  • The growing power of the clans leads to the formation of the Al'Raquish. It rules Kehjan alongside the kingdom's monarchy and trade guilds.[2]


  • Jere Harash summons the first demon into Sanctuary. His fellow Vizjerei perfect this summoning art, establishing demonology and the enslavement of demons as the basis of their power. Consequently, the Prime Evils learn of the existence of Sanctuary and humanity's latent power.[2]


  • The Temple of the Triune is founded as a front to spread the Prime Evils' influence. It steadily grows in power.[2]



  • A plague sweeps through Seram. Among the dead are the bulk of Uldyssian's family.

The Sin War[]

Main article: Sin War


  • An ideological battle between the Cathedral of Light and Triune begins. Thus begins the Sin War.

Later Events[]

  • A simple farmer, Uldyssian, is dragged into the conflict between the Triune and Cathedral of Light cults, when Lilith, who somehow manages to return from the Void, unlocks the hidden nephalem powers within him. She plans to use him as a slave against Inarius.[1]
  • Uldyssian and his followers give rise to the Edyrem. The group sets out to dismantle both the Triune and Cathedral and end their dominance. In the process, the High Heavens learn of the existence of Sanctuary and humanity.[3]
  • The Triune and Cathedral are destroyed, Lilith cast back to the Void, and the Worldstone is altered, removing Inarius's 'blanket' over humanity's potential. However, the High Heavens invade Sanctuary, seeking to eradicate the "abomination" of humanity. The Burning Hells openly invade as well, and thus begins a three-way battle between the Heavenly Host, Demonic Legion, and Edyrem.[4]
  • Uldyssian becomes more powerful than any angel or demon after unlocking his full nephalem power, but he realizes he is losing his humanity and decides to sacrifice himself to expel both Heaven and Hell from Sanctuary. The release of energy strips the Edyrem of their powers and resets the Worldstone to the state Inarius left it in.[1]
  • The Angiris Council votes on the issue of Sanctuary. Tyrael, moved by Uldyssian's sacrifice, makes the deciding vote that spares both. The Council subsequently makes a pact with Mephisto that both Heaven and Hell will recognize Sanctuary as its own realm, that humanity will be left free to choose its own path between Order and Chaos. To seal the deal, Mephisto is given Inarius as a slave, to be tortured for all eternity.[1]
  • Thus ends the Sin War. Only a few select individuals recall the events of Uldyssian's uprising.[4]

The Age of Magic[]

"The Age of Magic shone brightly but soon caught fire in the wars of the mages. Much of their splendor, lost to ash."

- Anonymous(src)


  • Believing the Sin War to merely be a clash of faiths, the majority of Kehjan's populace turn away from religion. The land is renamed Kehjistan in order to distance itself from the conflict.[2]
  • More and more people turn to the Mage Clans for guidance. Thus begins the Age of Magic.[2]
  • Mages who retain their memories from the Sin War declare that no mage must ever again summon a demon into the world, that humanity must remain free of angelic and demonic influence. The Vizjerei, Ennead, and Ammuit clans are left as the dominant mage clans and suppress popular religions.[1]


c. -748[]

c. -736[]

  • After twelve years of searching for Ureh, Gregus Mazi returns to the city's site and vanishes.[6]


  • It is discovered that the Vizjerei are continuing the practice of demonology. This revelation sparks a series of assassinations and political intrigue aimed at stripping the Vizjerei of their power.[2]

c. -215[]

  • The leader of the Hand of the Prophet foresees a conflict that will occur 1500 years into the future. He places the group's sisterhood into a magical slumber, where they will awake to aid heroes in the future age.[7]

  • The tensions between the Mage Clans erupt into bloodshed in Kehjistan's major cities. All-out war erupts.[2]


  • The final battle of the Mage Clan Wars occurs between the brothers Horazon, Bartuc, and their respective forces. Bartuc is killed and the city of Viz-jun destroyed.[1] The power of the Mage Clans is forever broken.[2]

The Age of Faith[]

  • The fallout from the conflict occurs as the people turn against the mages. Some mage clans (including the Vizjerei) survive but in diminished form. Numerous tomes of lore are destroyed, the order of the Viz-Jaq'taar is formed to deal with rogue mages, and laws are passed forbidding the use of magic. The Age of Magic thus comes to be replaced with the Age of Faith, and numerous new religions spring up.[1]


First-year of the Anno Kehjistani. Dates move upwards from this point. Later counted as one of the Bleaked Years.[8]

  • Akarat sees a vision while on Xiansai and attributes it to an angel named Yaerius. He gains supposed insight into the universe, reality, and humankind itself as an ascended power. Preaching the virtues of the Light, he gains a following in the numerous cities he visits.[2][1]


  • Akarat disappears in the jungles of Kehjistan. While Akarat's teachings have left their mark, they flounder in obscurity for the next millennium.[2]

c. 264[]

c. 285[]

  • By this point, the nephalem are believed to be extinct, though this is not entirely accurate.[10]



  • The demon Assur is killed by the hero Siggard. Entsteig is left untroubled by demonic incursion for at least two centuries.[11]

c. 885[]

The Dark Exile[]

Main article: Dark Exile


c. 985[]

The Rise of Zakarum[]


  • The town of Tristram is established around the Horadric monastery.[15] In the following years, the town attracts farmers and settlers from the region.[2]


  • Emperor Tassara of Kehjistan converts to the increasingly influential Zakarum faith, thus restoring his popularity amongst his restless subjects and stabilizing the region.[2]
  • The empire's capital is moved to Kurast. Tassara codifies the Zakarum faith's core beliefs and elects the first Que-Hegan. Records describe the Zakarum as a bona fide church and organized religion from this point forward.[2]


  • After three years of codified Zakarum faith, Tassara continues to be overshadowed by his childhood friend and Zakarum zealot, Rakkis. After defeating a coup of renegade nobles who seek to overthrow the church, Rakkis becomes a living legend. He uses his influence to replace government officials with Zakarum bishops, upsetting the region's balance of power.[2]
  • Wary of Rakkis's growing popularity, Tassara dispatches the general on a crusade to spread Zakarum to the lands of the West. With the departure of Rakkis and his most loyal forces, Tassara is able to secure his control over Kehjistan.[2]
  • Around the time of Rakkis's departure, the cleric Akkhan forms the Crusader order. He sends them to the east to seek out a means to purify the Zakarum faith, as per his belief that the church had strayed from Akarat's teachings.[2]


  • After years of warring with the peoples of the West and North, Rakkis ends his journey by founding Westmarch and becoming the nation's first king.[2] Just prior to this he discovers the ruins of Corvus, an ancient city of the Nephalem, and learns of humanity's ancestry.[19]


  • A decade after becoming king, Corvus continues to frustrate Rakkis in regards to his search for the nephalem's powers. Hearing of the existence of the Worldstone, he marches north to invade the Northern Steppes.[19]


  • The Horadric monastery in Tristram is abandoned.[15][2]


  • Hael writes on the existence of Corvus. He concludes that it is a symbolic concept, rather than an actual location.[20]


  • The Horadrim, with no quests left to undertake, fade into history and legend.[15][2]


The Zakarum Reformation[]


  • Que-Hegan Zebulon I initiates a reformation of the Zakarum Church, urging the faith to align itself with its ascetic and humble origins. The act is well received by the people and it sparks a surge in independent worship, secularism, and mysticism. However, the archbishops of the Zakarum High Council view these events as an erosion of the church's power but are unable to keep Zebulon in check.[2]
  • Around this time (mid-12th century), the church dispatches clerics to the west to spread the word of Zakarum. The rigours of travel lead to the assignment of the Protectors of the Word to protect future missionaries.[22]

c. 1172[]

  • The Red Circle is a gallows at this point in time.[23]

The 1220's[]


The Zakarum Inquisition[]


  • With the ascension of Que-Hegan Karamat, the High Council fulfills its goal of reverting Zebulon's reformations. Karamat is manipulated into establishing a strict system of worship that imposes harsh punishments on nonconformists. Missionary work takes on an increasingly martial tone. This marks the start of the Zakarum Inquisition, as the church purges various sects and brutally suppresses other religions such as Skatsim.[2]


  • Terania's mother dies. Her father, Jeronnan, is left to care for her.[21]

  • The loss of Albrecht shatters what remains of Leoric's sanity, and Tristram is plunged into horror as the king seeks to torture and execute all he suspects of conspiring against him.[36]
  • Lachdanan, captain of King Leoric's army, returns from the disastrous war with Westmarch and is forced to kill Leoric. The fallen monarch curses Lachdanan and his followers with his dying breath. Not long afterward, Lachdanan and the king's guards are attacked by Leoric, resurrected as the Skeleton King, as they attempt to bury him.[15] The king's curse transforms Lachdanan and his men into the dreaded Hell Knights in the deepest parts of the cathedral.[37]

  • More demons manifest on Sanctuary following Lilith's defeat, ushering in a new era of death and wanton destruction.[119]
  • The Mindwinter Blight festival is revived by the people of Kyovashad.[123]
  • A mysterious phenomenon manifests throughout the shrines of Sanctuary, enchanting them with immense and prosperous power. Celebrators believe this to be their ancestors, blessing them from beyond the grave to celebrate this joyous occasion.[124]
  • Inspired by the Blood Harvest, the legions of Hell initiate a new type of Helltide.[125]


A timeline for the series was posted on Blizzard's Diablo III page, its dates ranging from 964 to 1265. This was later taken down. With the release of Book of Tyrael, the timeline was finally solidified.[127] The practice of this page is to go with the most recent timeline and make note of contradictions/retcons (see below)

  • c. -1741: The events of the Sin War end, according to the "three thousand years before the Darkening of Tristram" figure in the Sin War trilogy. The timeframe has been altered by a few decades in the most recent timeline.
  • c. -715: During the height of the Mage Clan Wars, the Vizjerei discover the Umbaru. The Vizjerei, desiring demon-possessed victims to battle against their enemies, seek to turn the Umbaru into their servants.[14] This has since been rendered null by the timeline in the Book of Tyrael.
  • c. -705: By this point in time, several Umbaru clans are at war with the Vizjerei. Although primitive, the Umbaru are able to keep the mages at bay with their use of the terrain and shear ferocity (see above lore).[14]
  • c. -515: Umbaru captures a Vizjerei mage and attempt to use their now demon-possessed brethren against the Vizjerei themselves. However, they fall under the sway of the demon Zagraal and become the khazra (see above lore)[14]
  • c. 264: Gossip from Fara in Diablo II mentions the Sin War ravaging the lands of Aranoch 1000 years ago.
    • Gossip from Drognan in the same game places the Mage Clan Wars as occurring "nearly a thousand years ago." However, Book of Tyrael pushes the dates back to well over 1400 years ago.
  • 300: Demonsbane puts this date as the year of Bartuc's death.
  • The manual for the original game states that the Prime Evils wreaked havoc for centuries before being imprisoned by the Horadrim. Book of Cain and Book of Tyrael reduced this to decades.
  • 1103: The Awakening claims that Diablo was captured by the Horadrim in this year and that all the Horadrim bar Jered Cain was killed in the process.
  • 1213: The Awakening claims that Deckard Cain is born this year.
  • 1245: The Awakening claims that it was in this year that Lazarus released Diablo.
  • 1262: The original website timeline claimed that Leoric arrived in Khanduras in this year, as well as also falling into the madness inflicted by Diablo.[15]
  • 1265/'66: According to Deckard Cain's Journal, the events of Diablo, Diablo II, and Lord of Destruction occur over these two years only.
  • Diablo III/IV: Originally, it was stated that Diablo IV occurred 30 years after the events of Diablo III, putting it roughly in the year 1315.[128] This was later revised as occurring 50 years after the events of Reaper of Souls.[115]
    • By extension, the timeframe of Diablo III and Reaper of Souls was solidified by proxy. As 2 months pass between the end of Diablo III and Storm of Light[102] (and therefore Reaper of Souls, which begins mere minutes/hours after Storm of Light ends), Diablo III has to occur in late 1285, while Reaper of Souls occurs in early 1286, with the events of Adventure Mode following suit.
