Illidan’s allies close demonic portals in Outland

Full History

Magtheridon controlled much of Outland not solely through the troops already stationed near his citadel but by drawing additional demons into the shattered world. The dimensional gateways multiplied his strength and made a direct attack on his fortress an enormous gamble. Illidan recognized that he could not simply march against the pit lord while reinforcements continued to arrive. Breaking the gateways became the necessary first move in the campaign.

The operation unfolded across the harsh plains of Outland. Illidan had to approach each dimensional nexus and sustain the magic needed to close it, while Kael'thas and Lady Vashj defended him from attacking orcs and demons. The blood elves' spellcasters and soldiers held positions on land, while naga troops could approach through waters and other routes. Their cooperation turned an otherwise fragile coalition into a force capable of meeting several threats at once.

During the fighting, Magtheridon's followers besieged a nearby draenei village. Akama and his people knew the cost of leaving the pit lord's rule unchallenged. Assistance from Illidan's forces helped win the draenei over, and their warriors entered the wider offensive. As the portals fell, the balance shifted away from Magtheridon's defenders.

The destruction of those passages made it possible to challenge the Black Citadel itself. This was a distinct stage of the original campaign rather than a later World of Warcraft dungeon episode, and it explains why Akama's intervention mattered before the coalition reached the fortress.
