70+ years after the events of D2, the town is now a major city in the desert with skyscrapers? Built on the workforce of some human, mostly angel and demon slaves, just like how Dubai exploited foreign workers in real life? They might as well be trading and doing business with Xiansai, the China of Diablo during those decades of growth while the rest of the Sanctuary suffers? Imagine seeing Baal, Diablo, Mephisto, Auriel, Imperius at some bar serving as the elites in the city. Poor Old Tyrael works as a sweaty low paid worker under Imperius during those years as Heaven was emptied or abandoned.
