Before Gul'dan's dramatic fall, two strangers arrived on Draenor: The deposed warchief of the Horde and a bronze dragon whose motivations were clouded in mystery. Will their actions on Draenor place all living beings on Azeroth in mortal peril?
Kairozdormu tells Garrosh that he intends for him to create the first of many new Hordes. Not wanting to be a pawn, Garrosh betrays and kills Kairoz with a shard of the Vision of Time. Garrosh uses the shard to convince Grommash Hellscream not to drink Mannoroth's blood, and to instead create the Iron Horde.
