The one who sets the tone for this darker world is the principal character, Lilith. She's the daughter of Mephisto which is one of the Great Evils, and is called the Mother of Sanctuary, the world in which the D2R Items series takes place. Unlike previous games where there was a gradual building up to the main boss who is behind all the evil in all of the universe, Blizzard put Lilith up in the front from the first cutscene.
The build that can be played starts in Fractured Peaks. My hero's horse being killed and leaving him in a cave by himself for the night. From the caves emerged the first stop, Nevesk, a very small town , where things aren't what they seem. Lilith was already having an impact on the few people living there but her true power lies in her ability to make people indulge in their dark side. It was the first time my character was able to have with other NPCs and it was evident that the developers were looking to give the protagonist more of a role in the plot by giving their own dialogue, as well as taking a part in the cutscenes.
The town is Nevesk that Lilith's affect on the people of Sanctuary is shown. There's far more to her than simply being evil, which puts her apart as an intriguing adversary when compared to other Great Evils of previous Diablo games. Though her ultimate strategy isn't clear until the beginning of the game but her presence is recognized and is deliberately to be so by the team behind the development.
"By having you discover her story about what's happening in the world, and you'll get to learn about her motivations," Director of the game Joe Shely. "You get to understand what she's trying to buy D2R Ladder Items do and you'll feel more connected to her . perhaps even a hint of doubt there. you're thinking: watch Star Wars and go like you think Vader could be right. I believe that the idea of having more face time with with the big bad means that it's a far more satisfying resolve as you play through the story, as you progress through it."
