Armageddon

Armageddon is a potential future conflict.

Shortly before the Second Great War, Zeratul received a vision from the spirit of Tassadar, revealing an apocalyptic future. Zeratul saw what the future held. Humanity had been assimilated, the zerg had fallen under the sway of the Dark Voice and with the galaxy was in flames. Despite a valiant last stand on Shakuras, the protoss fell to the power of a Voice-controlled Swarm, who mocked their belief that the Queen of Blades was the true threat-the one individual who could have prevented its seizure of power. Zeratul wondered whether the Fallen One might be a xel'naga.

Zeratul imparted the knowledge he had received to Jim Raynor, urging him that Infested Kerrigan, for all her crimes, was their only hope for the future. Kerrigan was de-infested by a xel'naga artifact.
