The night elves, unable to defeat the raging Demons, and are forced to ally themselves with the ancient Dragons in order to banish the Legion from the world. The ensuing conflict is so apocalyptic, that the greater land-mass of Kalimdor is broken apart and smashed beneath the sea.
- The night elves vow to never use magic again, for fear that the Legion would return.

- The high elves, on the verge of losing their continuing war against the trolls, seek the aid of the humans of Arathor. In exchange for their help against the trolls, the high elves agree to teach men in the ways of magic. The combined army of elves and humans succeeds in wiping out the majority of the trolls of Lordaeron.

- Though banished from Azeroth, the Burning Legion corrupts the orcish clans on the world of Draenor. The once noble, shamanistic Orc clans unite and become a rampaging Horde under the rule of the malevolent Shadow Council. By enlisting the aid of demonic magiks, the orcs were able to decimate all draenei with little loss.

- Blackhand, the Horde's current warchief, was slain and succeeded by Orgrim Doomhammer. Doomhammer disbanded into groups of Raiders who were thought to be loyal to Blackhand. By torturing Gul'dan's spy, Garona, Doomhammer, located and slaughtered the Horde warlocks. Gul'dan was forced to bow to his new superior. To gain Doomhammer's trust, he slaughters his own Necrolytes, and used their spirits to create Death Knights.
- Lord Lothar leads an exodus of refugees to the northern nation of Lordaeron. Once there, he convinces the leaders of the seven Human nations to unite in arms against the Horde. The separate nations of the Arathorian empire are reunited as the Alliance of Lordaeron. Through the chaos, Thrall was born. This young orc was found and captured by humans, and raised as a slave and gladiator.
