Invasion of Outland

The War in Outland or The War Against Illidan, was a conflict that occurred on the ruined planet of Outland between the Grand Alliance, The New Horde, The Legion and the Illidari. The War started when the Burning Legion invaded the blasted lands via dark portal when it was opened by Lord Kazzak. The War came to a conclusion when Illidan was brought down in the Black Temple and the Illidari army dismantled, thus beginning the Sunwell Plateau Campaign.
