Caldeum is an environment which we haven’t come across earlier. This town happens to be a successful trading center in Kehjisthan which is ruled by the emperor. The town people continue their trade when the other part of the world was busy battling the evil. The denizens are devoid of human nature and are more involved in their trading. The problem begins when few nobles arrive from Kurast to begin their new lives. These nobles are regarded as selfish and arrogant money-oriented people who forced their mercenaries to further their ambitions.

The emperor manages to keep the town safe from the evil. However soon after his death, things become dull and weird things start happening. The artwork image of this town is a feast to the eyes. Hopefully this town will be one of the most fascinating environment of Diablo 3, as the other towns are more gloomy compared to this one.
