Having successfully stolen the Book of Medivh from Dalaran, Arthas and Kel'Thuzad retreated back to their base where they prepared to summon Archimonde into the world. As everything was ready, Kel'Thuzad flipped through the book, marvelling with amazement at Medivh's knowledge, musing that the Last Guardian was more powerful than he thought. Tichondrius appeared, sneered that Medivh's power had not been enough to save him from death and ordered the Summoning to commence. Kel'Thuzad began the ritual, leaving Arthas in charge of the defenses.
Determined to stop the Scourge, the Kirin Tor and their allies launched a massive assault against the undead base. Arthas was ready for them. His scouts had discovered a stockpile of goblin land mines which he used to bolster his defenses. As the Summoning progressed, the barriers between Azeroth and the Twisting Nether weakened, allowing the Burning Legion to send their demonic Felhounds and Infernals to assist the undead. The forces of the Scourge and the Legion held the wizards and their knights at bay long enough for Kel'Thuzad to finish the Summoning. Finally, Archimonde entered the world. "Tremble Mortals and despair!" he bellowed, "Doom has come to this world!" The remaining wizards fled at the sight of the Defiler.
Archimonde congratulated Kel'Thuzad on a job well done. Tichondrius appeared again and welcomed his master. Archimonde's first act was to relieve the Lich King of command and turn the Scourge over to the Dreadlords. Tichondrius was quite pleased by this order. Archimonde declared that before he launched the Legion's invasion, he would make an example of the wizards by obliterating the city of Dalaran. The demons then headed off, leaving Arthas and Kel'Thuzad behind.
Arthas was outraged over this turn of events. "What happens to us now?!" he demanded. Kel'Thuzad told him to be patient, as the Lich King had foreseen all this and had more plans for Arthas.
