Skolos Skovos is a great example of this. Place where Askari society is from. They gave us the rogues in D1 and amazons in D2, but their society has never been explored in the games. They're very ancient and haven't had much contact with the outside world. No trade or exchange of philosophies. How do they develop differently in isolation? They trace themselves back to the mythology of the angels. They were founded by angel and her human lover, and this gives them a very different view of the world than other societies.

We don't want to belabor this sort of thing when player is running around playing the game, but we think about how we'll get the information across to the player? One way is that some of the NPCs reflect upon where they come from. This helps us in 2 ways. For a great RPG you need great NPCs. When they give you a quest, you should feel as if you are playing in a living world with depth to it. To make living characters, they need to have culture. Characters reacting and speaking and dressing to reflect their culture tells the player about it without long monologues. We research places in our world and use them as influences for the game designs. We styled the residents and architecture of Caldeum to give a certain vibe to the player. An Eastern feel in the buildings, clothing, daily life, etc.
