Mystical comet overlooking a settlement in the western part of Sanctuary. The story line of the game takes place twenty years after a few powerful heroes saved Sanctuary from the demonic onslaught in Diablo II. Those events took place out of the sight of the common populace, and have become myth or legend over the intervening years. Most of the principles are dead or insane, and no one has had any sight of the Archangel Tyrael since he destroyed the Worldstone, triggering an explosion that erasedMountArreatand shattered the Barbarians’ civilization. Since the destruction of the Worldstone, those few humans (such as Deckard Cain) who did know of the danger to the world have been expecting an imminent demonic invasion, without the Worldstone to keep them in the Burning Hells.
This has not happened because, and players will eventually learn, the two remaining lords of Hell, Belial and Azmodan, have been building armies for a full-on invasion, intended to utterly destroy humanity. Players will see small-scale demonic events, as in previous games, but the developers have promised that the scale of some aspects of the game, such as the siege on Bastion’s Keep, will be amazingly large; far bigger than anything ever previously seen in the series. Additional information on the story line can be seen within the Black Soulstone Cinematic. Unlike the blank cyphers that all characters were in previous games in the series, the individual characters in Diablo 3 will have personalities.
The Wizard is young, brash, and headstrong. The Monk is powerful and quietly confident. The Barbarian is strong and stoic. The Demon Hunter is angry and reckless in her need for vengeance. And the Witch Doctor is spiritual, mysterious, and misunderstood by the populace at large. The characters will behave accordingly, and inspire different replies and behavior from the NPCs. The Followers such as the Templar and Enchantress each have a distinct personality with a fleshed-out background and will not only banter to the player character, but also to other NPCs (and even to each other within the camp or town). The same holds true for other NPCs, such as Leah, who may on occasion follow the player into the fray during a quest.
