Diablo 4 has a lot of excitement built up around it

Diablo 4 has a lot of excitement built up around it. The next game in the storied action-RPG franchise has a lot of history that extends beyond just the games D2R Items, which already have a lot of plotlines left to play around with. Diablo 4 has a wealth of content outside of the games to pull from, including books and comics. The expanded media covers a lot of the series' backstory, like the creation of Sanctuary and the conflicts between angels and demons that predate humanity itself.

A prime example of Diablo 4 already pulling from the well of lore available is its choice of main antagonist. Bringing Lilith back into the world of Sanctuary has huge ramifications and leaves the possibility open for Diablo 4 to explore some of the events that aren't referenced heavily in the previous games.

Lilith is one of the two beings that created Sanctuary, the world where the games take place, and her children went on to be vitally important to the history of Diablo. Her presence could be what opens the floodgates to other lore, and she only represents a small part of what could be coming.

Lilith is hugely important to the overall lore of Diablo, but she only represents one side of the Eternal Conflict. 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 buy D2R ladder items. The new class-specific quests in Diablo 4 might be a way that this is done.
