Timeline
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.

After the Eye ritualA Rescue Before Exile
Tyrande had been swept downriver while protecting refugees from the Scourge. Maiev told Malfurion that she was dead, keeping him focused on capturing Illidan. Kael’thas revealed that her fate was not certain.
Illidan offered to help find her. His naga searched the river and the brothers worked together against the undead to reach her. For a moment, saving someone they both loved mattered more than the judgment waiting between them.
Malfurion allowed Illidan to leave after the rescue, without absolving him of his actions. Illidan opened a portal to Outland to escape Kil’jaeden’s punishment. Maiev followed him through. The separation ended neither her hunt nor the demon lord’s claim on him.

Before the conquest of OutlandAn Alliance Broken
Fighting beside the remnants of Lordaeron’s army did not give Kael’thas secure allies. Garithos distrusted the elves and left them facing the undead with inadequate support. When Vashj offered help, refusing her meant risking the soldiers he was trying to keep alive.
Accepting naga assistance became the charge used against him. Garithos imprisoned the prince and his followers in Dalaran and condemned them. Vashj returned to free them and offered a different prospect: Illidan might have an answer to their hunger for magic.
Kael’thas followed her into Outland. His new allegiance grew from that escape, but it did not remove his dependence. The promised cure was instead a way of finding more magic to consume, binding the prince’s hopes to another ruler’s power.

Before the return to IcecrownThe Enemy of My Enemy
Outland offered Illidan distance from Azeroth, but not safety. Maiev captured him there before Vashj and Kael’thas intervened. The blood elf prince pledged his people’s service in exchange for help with their hunger for magic.
The shattered world already had a ruler. Magtheridon drew demonic reinforcements through portals and held Black Temple. Illidan’s forces closed those routes and joined Akama, whose people wanted the sanctuary taken back from its occupier. Together they defeated the pit lord.
Illidan claimed the victory as lordship over Outland. Akama would discover that removing Magtheridon had not restored his people’s freedom. Nor had conquest concealed Illidan from Kil’jaeden: the demon lord found him and demanded another attempt against the Frozen Throne.

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.
