As it goes with any long-running RPG series, Diablo is crammed full of proper nouns—Inarius and the Horadrim and the Nephalem and so on. If Diablo 4 is going to be your first crack at the series (or hell, if you understandably need a refresher) Blizzard has a new video in which its developers set up the story for you with a bit of context from the series origins and the end of Diablo 3.
For starters, Diablo 4 kicks off 50 years after the events of Diablo 3's Reaper of Souls DLC during which half of the population of Sanctuary (the mortal realm between the heavens and hells) was killed off by the archangel of death, Malthael. Sanctuary's original creators, the angel Inarius and demon Lilith have both returned and, wouldn't you know it, that's not really going to go well for humanity.
