Once, when Sanctuary was young, an Angel and a Nephalem became lovers.
There's both Diablo Immortal and Diablo 4 guaranteed on the horizon, with a potential revisiting of Diablo 2's story in a remastered (nay, Resurrected?) version.
It seems like it should be a "duh" moment, right?
The answer is a resounding maybe.
We don't know for certain yet, but I cannot seem to make myself imagine a Diablo 4 without Necromancers, especially since I'm fairly convinced that Rathma -- aka Linarian, the son of Lilith and Inarius, the guy who essentially created the idea of Necromancy in the Diablo universe -- seems to be the weird guy in the cinematic who summons Lilith back to Sanctuary.
In a way, Lilith is the reason behind everything we've seen in the Diablo universe, well before she was rebirthed in a hail of blood in the Diablo 4 trailer.
The internet is full of theories about the identity of the pale man who summoned Lilith in the Diablo 4 BlizzCon trailer.
Of the people in the new amazing Diablo 4 trailer, we know precisely one of them by name: Lilith.
Who is Rathma?
Diablo 4's announcement returned a few names in the franchise to prominence.
