The first quest is given by Queen Alexstrasza at Wyrmrest asking you to meet either Bolvar or Saurfang the Younger depending your faction. This leads to an epic questline where you enter the Undercity with Thrall and Lady Sylvanas (Horde) to battle tons of Legion and Apothecary traitors in order to kill Varimathras. This first part only shows the Wargate, meeting Saurfang, and arriving to Orgrimmar where Lady Jaina talks to Thrall that the Fourth War is about to start between Alliance and Horde for the death of Bolvar Fordragon.
