Two days later, within the compounds of the Black Citadel in Outland; Illidan, Vashj and Akama discuss their final plans for the defenses of the main stronghold. Awaiting for the return of Prince Kael'thas and his brethren, along with the coming of the surviving Alliance Expedition; the naga and draenei armies within the Black Citadel are all ready for what seem to be their last upcoming bloodiest and fiercest war battle against the forces of the Burning Legion in Outland. Making the final arrangements within the citadel; the demon huntress Alandien, who had been sent by Illidan upon a stealthy scouting mission, arrives and makes her report about what she saw in the outside. Returning to Illidan on the Black Citadel; Alandien begins to inform her master of a grave news.

Alandien: "Lord Illidan! Our enemies draw near! A full battalion of demons and fel orcs are now heading this way! Their countless horrifying forces fill the lands! They will be here at nightfall!"

Illidan: "Let them come! We will greet them all by our own blades, and we will not back down!"

Vashj: "I just hope that Kael and his old Alliance comrades arrive here before our enemies do."

Akama: "Nothing to worry about. They will be here just in time before this battle even begin."

Few hours passed later, the day is coming to an end with the darkness of the night slowly covers the skies. All of a sudden, a loud sound of a horn blowing has just been heard outside the gates of the Black Citadel. Immediately realizing that the sound blown is of an elvish horn, the gates were opened for the awaited coming of Prince Kael'thas and his blood elven brethren, joined by all the surviving forces of the old Alliance Expedition led by Khadgar, Danath, Kurdran, Turalyon, and Alleria. Pleased to see their allied reinforcements; Illidan, Akama, and Lady Vashj went to greet and welcome the five veteran heroes of the Alliance troops accompanied by Kael. The rest of the Alliance army settle and entrench themselves upon the stronghold of Prince Kael'thas within the Black Citadel, conjoining themselves with the forces of the blood elves and the draenei warriors.

Akama: "Greetings, my old friends! I knew you would all make it here! You are most welcome!"

Khadgar: "Glad to see you as well, Akama. Fate has bounded us to fight altogether once again."

Illidan: "I am pleased by all of your timely arrival. Our enemies are making their way here as we speak. A battalion of demons, combined with the fel orc army, will be at our gates by nightfall."

Turalyon: "I see. It seems our timing here was just perfect. Very well, in honor of the memory of the Alliance of Lordaeron, we are proud to stand and fight against our old nemesis once more."

Kael: "Lord Illidan, no matter what horror comes for us, we will fight with you to whatever end."

Alleria: "Yes, we have all agreed on this even if there is a huge chance of us losing this in battle. We shall do what it takes to prevent the demons and fel orcs here from stepping foot to Azeroth."

Khadgar: "Yes, our sworn task to protect from our own world from another mass invasion. After we shut the Dark Portal and sacrificed ourselves here for the safety of our own world, we thought everything back home have been well in peace ever since. It seems, we were wrong after all. We have learned so much about what happened back in Azeroth from Kael, much especially those of the destruction of the kingdoms in Lordaeron in the hands of the undead, and the demons that we are also facing here. Despite the wreckage of our homelands in our long absence, we made a vow to win this battle here, afterwards, we shall return to Azeroth and see our homelands once again."

Turalyon: "Long have we dreamt of seeing our own world again all this time. Now that the Dark Portal had been reopened once again, we shall finally make our way back home, and see our own broken people and shattered lands, once we dealt with the threat of the Legion here on Outland!"

Illidan: "Then by all means; help me put an end to our common foes here, and you shall be all be able to return freely to Azeroth. If we fail here, then the Legion will retake control over Outland, and launch another massive demonic invasion, coming from this place through the Dark Portal."

Turalyon: "We shall do our best upon standing and fighting with you throughout this war battle."

The allied armies of Illidan's forces and the Alliance Expedition finalize their strategical plans in their defense upon the citadel. The new set of defensive arrangements within the Black Citadel is formidable and deadly against any foe that might launch an attack upon it, yet also very different from its original form of defenses during the time Illidan and his forces first invaded it to destroy Magtheridon. Many of the old architectural and structural settings of the Black Citadel have been redesigned and renovated after Illidan conquered it and became the new official Lord of Outland.

The darkness of the abyssal night skies soon covered the entire Outland, as the horrifying sounds of countless footsteps of demons and fel orcs marching are now heard just several meters outside of the Black Citadel. The forces of the Burning Legion in Outland finally arrive and are being led by Azgoth, Mephistroth, Kargath Bladefist, Tagar Spinebreaker, Nek'rosh Skullcrusher, Keli'dan the Breaker, and a new doomlord demon named Highlord Kruul in replacement for Lord Kazzak. Huge numbers of strong and powerful demon and fel orc warriors are arranged in various groups, which consists of grunts, raiders, fel orc warlocks, overlords, fel ravagers, eredar warlocks, doom guards, voidwalkers, infernals, infernal juggernauts, nether dragons and the fiery flying daemons.
