[WoW] Battle for Azeroth - Page 2

So after Deathwing, Garrosh basically went off the deep end on the Alliance. He kept trying to annex their shit, and culminated in him bombing Theramore (which pissed Jaina off something fierce). When Pandaria was discovered, there was an arms race between the Alliance and Horde to see who could exploit it first and who could stop the other from doing so. Their conflict brought back ancient demons called the Sha which feed on negative emotion (and war is awesome for negative emotion). The expansion culminated in Garrosh seizing the Heart of Y'shaarj (the old god that created the Sha) and using it to try to end the Alliance and all the non-orc/goblin races of the Horde. The last raid was the Siege of Orgrimmar in which you defeat Garrosh, Vol'jin becomes warchief, and he's set for trial in Pandaria.

Unfortunately, some dumbass Bronze dragon seems to think that Garrosh is essential to fixing the timeline, so he rescues him from the trial and takes him back in time to Draenor where he prevents Grom from drinking Mannoroth's blood and gives them highly advanced siege weaponry, as well as a plan of attack for Azeroth. They open the Dark Portal and start attacking, so we go back through to alternate Draenor and that's basically the entire Warlords of Draenor expansion. That expansion culminated in Gul'dan opening a massive portal and bringing Archimonde to attempt to re-corrupt the orcs, but we kill Archimonde and Archie sends Gul'dan hurtling through a portal to the Twisting Nether.

Legion starts with Gul'dan doing something that finally lets him come back to Azeroth and open a massive demon portal.
