If you played Diablo 2, you may remember Andariel.
The lore of the Diablo franchise has gotten deeper and more involved with every new game, expanding from the small town of Tristram and the catacombs beneath the cathedral there to a globe-spanning adventure that led to Hell itself and finally in Diablo 3 we went to the Heavens and Pandemonium in turn. We've seen nightmarish monsters, Baal's army overwhelm the Barbarians and the destruction of the Worldstone, the siege of the Crystal Arch and the Nephalem stand triumphant against a former Archangel with the power of all seven Evils in its grasp.
So we had a big announcement at Gamescom this month, and we know now that World of Warcraft is getting a big new expansion, Legion.
From this whirling nightmare, this bloated ruin of the first evil's corpse crawled the demons. The Burning Hells could in a real sense be said to be the blackened corpse of Tathemet itself, and at the center of the Hells lies the Black Abyss, from which rose the Great Evils. Essentially birthed from the seven heads of Tathemet, there were the three Primes -- Mephisto, Baal and Diablo -- and the four Lessers.
