When blood-crazed, willing slaves to demons who had sold their race and their world for power assaulted Azeroth, it was the humans who fought them. It was humans who lost ground, family, mothers and fathers and homes to stem the tide of orcish bloodlust and save Azeroth from their evil. There is no question of this. If the humans had lost the Second War, Azeroth would have been destroyed just as Draenor was, sucked dry of life. It was also a human's arrogant decision that she knew best that led the lord of the Burning Legion himself to invade her body, possess her unborn son, and twist his gifts and powers to evil, to contact Gul'dan and lead to the First and Second Wars. If not for humans, the orcs would have died on their dried-out, fel-poisoned planet, and no one would have ever heard of them again.
Humanity could be said to be the best and the worst of Azeroth. Short-lived, humans possess as much or more talent for every field of endeavor as any race on the face of the world. They equal or surpass orcs and trolls for savagery in combat. They match or overmatch high and blood elves for sorcery. Their priests command the Holy Light, as do their paladins. Humans have been spies, diplomats, scholars, warlords and simple men and women of the soil. In part one, we talked about the rise of the Seven Nations of humanity following the troll wars.
Now, we look to their destruction.
