Sanctuary world map, with locations noted. The world map of Sanctuary was actually released with the second Diablo game’s manual, but a new and improved map has been made by Blizzard, outlining the continents and the major settlements. Many of these locations will be visited in Diablo 3, including Tristram. Areas close by that were never visited in the previous games will also have a chance, like theLeoricHighlandsand Westmarch, and it’s known that much of Act Three takes place in the Barbarian Lands around the Arreat Crater. The scorching deserts of the Aranoch will be revisited by the player when they have the opportunity to visit one of the largest capital cities in Sanctuary: Caldeum.
The player will also explore the depths of the Archives of Zoltun Kulle, ex-horadric mage. We have been shown detailed pictures of Skovos (the land of the Amazons), as well as Caldeum and Tristram. Skovos is confirmed to be excluded from the game, but the level of detail they are putting into the universe suggests a big expansion pack, MMOs, or a film. Ureh is another area that has been shown off by the development team (and was showcased in the original cinematic trailer) which will not be in the release version of Diablo 3.
Outdoor areas will be less randomized than dungeons, and the terrain will for the most part be static. Instead, a lot of random scripted events will take place, and some will even be really advanced. They can vary from an escort quest, to a moldy tome, or a big, bad boss monster. You will also find interactive environments with dangerous traps, obstacles, and destructible elements. There will be “numerous” outdoor locations. These portions of the map that are randomised are called events, and can even happen within randomised dungeons. The land is filled with dungeons, as in Diablo II. Dungeons vary widely in size and design, and are promised to offer better randomization and variety than they did in Diablo II. Perhaps more critically, the development team has also stated that there will be many more varieties of dungeons than what was seen in Diablo II.
