Death offered no escape for the scores of humans killed during the Lich King’s campaign to scour the living from Lordaeron. Instead, the kingdom’s fallen were risen into undeath as Scourge minions and forced to wage an unholy war against everything… and everyone… that they once held dear.
When the Lich King’s grasp on his vast armies faltered after the Third War, a contingent of undead broke free of their master’s iron will. Although this freedom seemed to be a blessing at first, these former humans were soon tormented by memories of the unspeakable horrors that they had committed as mindless Scourge agents. Those who did not descend into madness were faced with a chilling realization: the entirety of Azeroth sought their destruction.
In their darkest hour, the renegade undead were rallied together by the former ranger-general of Quel’Thalas, Sylvanas Windrunner. Defeated during an attack on her kingdom and transformed into a powerful Scourge banshee, Sylvanas had also regained her freedom from the Lich King. Under their new queen’s guidance, the independent undead – known as Forsaken – established the Undercity beneath the ruins of Lordaeron’s capital. While some Forsaken feared Sylvanas, others valued the security she provided. Many of the free-willed undead, however, found a purpose to their cursed existence through the banshee queen’s burning desire to destroy the Lich King.
Despite not being affiliated with the Scourge, the Forsaken came under threat from humans who were dedicated to eradicating all Forsaken. As a means to further her own goals and protect her budding nation, Sylvanas sent emissaries to various factions in search of allies. The kind-hearted tauren of Thunder Bluff proved to be the most promising contact. Specifically, Archdruid Hamuul Runetotem saw the potential for redemption in Sylvanas’ people, even though he was fully aware of the Forsaken’s sinister nature. Thus, the tauren convinced Warchief Thrall, despite his misgivings, to forge an alliance of convenience between the Forsaken and the Horde. In the end, the Forsaken’s chances of victory against the Lich King were bolstered, while the Horde gained an invaluable foothold in the Eastern Kingdoms.
Ultimately, the Forsaken assisted the Horde with a massive offensive against the Lich King’s power base in Northrend and exacted vengeance upon their hated enemy. The victory, however, was not without its hurdles. During the invasion, Grand Apothecary Putress unleashed a new plague that killed friend and foe alike, while his traitorous counterpart, the dreadlord Varimathras, seized the Undercity in a coup that nearly killed Sylvanas. The usurpers were slain for their vile deeds and the Forsaken capital was restored, but the debacle created suspicion among the Horde regarding Sylvanas’ loyalties.
Now, along with being mistrusted by her own allies, Sylvanas recognizes that many of Azeroth’s other inhabitants still see her people as a threat, even after the Lich King’s defeat. As their numbers dwindle by the day, the Forsaken have begun fortifying their holdings around the Undercity, working to prove their loyalty to the Horde’s cause even as they ready themselves for any future attacks.
