Diablo takes place in the mortal realm, but the war encompasses two other realms as well – the High Heavens and the Burning Hells. As players explored the procedurally generated dungeons and took on hordes of demonic foes, they learned about the devastating and never-ending war between demons and angels. The first game in the series was met with critical acclaim, and it really launched the franchise in the best possible way. RELATED: Diablo: The Lore Behind Deckard Cain Explained Diablo

Diablo 4 may be reintroducing the enigmatic Lilith, but Diablo is full of other significant characters for players to get to grips with. Encapsulating the complex and ongoing battle between good and evil, the Diablo series combines elements of dark fantasy and demonic themes with its macabre aesthetics. The Diablo series is full to the brim of rich lore and expansive storytelling, and it might be a good idea for fans to get to grips with the overall arc of the narrative before Diablo 4releases. This would already be a lot of content to get through for fans, but on top of that is the upcoming release of Diablo 4, the fourth main installment in the Diablo series and a highly-anticipated sequel. Not only are there three core games, but there are expansion packs, additional types of media that expanded the story, and the recently released MMO ARPG Diablo Immortal.

Blizzard's Diablo series has been running since 1997, so unsurprisingly the games have covered a lot of narrative ground.
