Diablo's Lore is Deeper than Many Know from doris89592's blog

Diablo 4: What the Druid and Sorceress Mean for Diablo IV Gold the Game's Last Class Lilith is hugely important to the overall lore of Diablo, but she only represents one side of the Eternal Conflict. That conflict spread and could have big implications in Diablo 4.

While the events of the previous games have changed the world in serious ways, Diablo being defeated (for now) among them, it seems like Diablo 4 may lean heavy into its past. The new class-specific quests in Diablo 4 might be a way that this is done. 

Having the different classes interact with members of long-running factions like the Priests of Rathma or the Crusaders could be a good way to both move the narrative forward while also referencing game's past. Especially with Deckard Cain dead, players will need new places to learn more about Sanctuary's deep history.

A large chunk of the expanded media focuses around the Eternal Conflict and the Sin War. The former is more well known to casual fans, and the battle between Heaven and Hell has long influenced the overall story of the Diablo games. 

The Sin War is really only dealt with in the books and comics, but is equally important. Lilith and the angel Inarius had children together: the Nephalem. Nephalem soon grew to become more powerful than the angels and demons that created them, and that led to a war between factions that saw them as threats to Diablo 4 Gold buy Sanctuary.
