Timeline
Before the First WarDraenor Before the Horde
Before it became Outland, Draenor was a living world of orc clans and draenei settlements. The draenei had fled the Burning Legion, while the orcs preserved traditions centered on clan loyalties, ancestors, and the elements. Their shared world had not yet been reduced to a battlefield for a demonic campaign.
The relationship between these peoples provides the human scale of Rise of the Horde. Its tragedy begins before the portal to Azeroth: families, friendships, and inherited customs are gradually overtaken by a war whose purpose has been hidden from those expected to fight it.

Years before the Dark PortalThe Corruption of the Horde
Kil’jaeden manipulated Ner’zhul into turning the orc clans against the draenei. When the shaman questioned the deception, Gul’dan became the willing instrument of the Legion’s plans. Under his influence, warlocks and the Shadow Council redirected the clans’ power toward conquest.
The blood of Mannoroth bound those who drank it to demonic corruption. The slaughter of the draenei and the ruin spreading through Draenor transformed the Horde’s future. Azeroth would encounter the resulting invasion through the Dark Portal, but the catastrophe that made that army began on the other side.

Before the Alliance expeditionThree Relics for Another World
Ner’zhul sought a future beyond a ruined Draenor. His forces reopened the Dark Portal with the Skull of Gul’dan, then entered Azeroth to obtain tools for a different set of gateways.
The targets were the Book of Medivh, the Eye of Dalaran and the Jeweled Scepter of Sargeras. Together with a coming celestial alignment, they offered the means to reach other worlds.
The Alliance learned that the raids were preparations for further invasions. Khadgar joined the expedition through the portal to stop the plan at its source. The defenders of Azeroth were now advancing into the homeland of the enemy.

During the pursuit of Ner’zhulThe Dragon and the Skull
Following the stolen relics forced the expedition to divide. Ner’zhul had handed the Skull of Gul’dan to Deathwing, separating it from the book the pursuers also needed. Khadgar, Turalyon and Alleria went after the dragon.
In the lands that would become part of Outland, the dragon’s brood had enemies of its own. The expedition found an opportunity in that conflict. Khadgar could not simply overpower Deathwing, but he could interfere with the armor holding the dragon’s damaged body together.
The resulting pain forced Deathwing to retreat and left the skull behind. Possessing it brought temptation as well as a practical advantage. Khadgar rejected its offer of power and returned to the urgent work of stopping the portals.

c. 8 ADPThe Shattering of Draenor
Khadgar and the expedition reached Ner’zhul too late to prevent the ritual. The Book of Medivh, Eye of Dalaran and Jeweled Scepter had served their purpose. Portals opened across Draenor, but their instability began tearing the world apart.
Ner’zhul escaped through a rift, abandoning those behind him. Khadgar recovered the book and used its knowledge with the Skull of Gul’dan to close the Dark Portal. The expedition stayed beyond it so the catastrophe would not spread into Azeroth.
The survivors endured the upheaval and returned to a shattered landscape: Outland. Their sacrifice had protected their home while cutting them off from it. On Azeroth, those who did not know they had survived remembered the missing expedition as heroes lost beyond the gate.

Before the Third War · date unknownThe Prison in the Ice
Escaping the destruction of Draenor did not free Ner’zhul. Kil’jaeden captured the fleeing shaman and destroyed his body, keeping his spirit alive to face a new form of servitude. The orc who had tried to find a way out of disaster became the instrument of another invasion.
Confined within the Frozen Throne in Northrend, Ner’zhul could reach beyond his prison with his mind. He began gathering the dead into an army and spreading the plague that would make fresh victims into servants. The Lich King was a captive, but his confinement did not prevent him from conquering the lands around him.

Before the Third War · date unknownThe War of the Spider
Beneath Northrend, the nerubians of Azjol-Nerub resisted the growing Scourge. Their living bodies resisted the plague, and their underground kingdom gave them tunnels and strongholds from which to fight. This was a people defending its home, not an undead army waiting to be discovered.
That resistance could not protect their dead. The Lich King raised fallen defenders and turned them against their own people. Anub’arak, once their king, was killed and compelled to serve the power he had opposed. Each defeat therefore cost the living more than territory: it gave the enemy more soldiers.
The kingdom fell, but its people were not entirely extinguished. Living survivors continued to resist in its ruins. The surviving nerubians faced undead enemies who wore the shapes of their former kin.

Before the Third War · date unknownThe Voice from Northrend
Kel’Thuzad followed the distant summons of Ner’zhul into Northrend, seeking powers his fellow mages had rejected. What he found was more terrible than a new school of magic. The undead kingdom demonstrated how death itself could become captivity.
His desire for knowledge did not spare him fear when he saw the plague at work. By the time he understood the cost of serving the Lich King, escape was beyond him. Kel’Thuzad pledged himself to his new master and returned south to prepare the way for the Scourge.
The Cult of the Damned gave the invasion willing servants among the living. Recruitment and concealed preparations preceded the open catastrophe in Lordaeron. When Arthas began investigating the plague, he was confronting the result of a campaign already underway.

After the Third WarAn Eye Turned North
Kil’jaeden demanded the destruction of Ner’zhul, whose disobedience had made the Lich King a threat to his former master. Illidan accepted the task. The memories taken from the Skull gave him a route to a weapon powerful enough to attempt it.
With Vashj’s naga, Illidan entered the Tomb of Sargeras and claimed the Eye. Maiev followed him inside, but his escape left her companions trapped in the collapsing tomb. Her pursuit became inseparable from those losses.
At Dalaran, Illidan directed the Eye’s power toward Icecrown. The ritual threatened the land around the Frozen Throne as well as its prisoner. Malfurion, Maiev and Kael’thas intervened before the attack could finish. The artifact was destroyed and Illidan’s promise to Kil’jaeden remained unfulfilled.

c. 22 ADPThe Ascent to the Frozen Throne
The weakening Ner’zhul called Arthas back to Northrend. Illidan and his allies were moving against the Frozen Throne, and the death knight could no longer assume that the power sustaining him would endure. Reaching Icecrown became a race to preserve his master and himself.
Anub’arak offered a route through the fallen nerubian kingdom. The former king guided Arthas through tunnels haunted by the consequences of the Scourge’s conquest. For Arthas the passage was a shortcut; for Anub’arak it was the ruin of the realm he had once ruled.
At Icecrown, Arthas overcame Illidan and climbed to the prison above. He broke the ice and put on the Helm of Domination, joining himself to Ner’zhul as the Lich King. The prince who had taken a cursed blade to save his people now sat at the center of the power that had destroyed them.
Illidan survived the duel. Vashj and Kael’thas brought him back to Outland, where the failure left him preparing for Kil’jaeden’s wrath. Arthas gained a throne; his opponent returned to a kingdom that could not make him safe.
