"And so Kil'jaeden the Deceiver did exactly that, deceiving first Ner'zhul and through him, the orcs as a whole. Slowly at first, and then more quickly through Ner'zhul's more compliant apprentice Gul'dan, Kil'Jaeden taught demonic magics to the orcs, while also teaching them to use the aggressive nature they once employed in hunting and testing their strength against the elements to dominate and destroy the draenei instead. Not expecting attack from a quarter they'd so long been at peace with, the draenei fell, and were nearly destroyed by this unexpected threat which turned both numbers and new powers against them. (It didn't help that among the orcish numbers were Durotan and Orgrim Doomhammer, who'd been inside a draenei city and knew how to bypass its defenses). An attempt to broker peace at the site the draenei came to land, the sacred mountain Oshu'gun, only exacerbated the issue and ultimately led Ner'zhul to be replaced by his even more aggressive and power hungry apprentice, and Gul'dan prosecuted the war with the draenei with no regard to the truth of Kil'Jaeden's original accusations."

Wait, what were the original accusations? How did he trick them into attacking the draenei?
