In Brightest Day: Warcraft’s Old Gods

Since World of Warcraft’s become the main source of most lore involving the citizens of Azeroth, most of the main plots have revolved around, in some way or another, the concept of the Old Gods.

In fact, I would argue that the Old Gods are one of the biggest threats, if not the biggest threat, to the stability of Azeroth. They also have shown over and over again that they have the ability to make even the strongest warriors of Azeroth go mad.
