Genn assassinates Anduin after Anduin learns of his "secret," Wrathion gets upset he loses his boy toy and helps Sylvanas kill Genn, Tyrande and the Nightelves take over Stormwind after finding out Genn was behind the burning of Teldrassil...and the Alliance with no clear Human leader, disbands instead of trying to work things out amongst the leadership still left.
