He believed in ultimate balance and wanted Humanity to control their own fate, and partnered with the mythical creature Trag’Oul to work towards this goal. As a note, the Diablo III adventurers are all Nephalem, which is canonically why you can beat the Prime Evil in a fistfight.Ī powerful summoner, Rathma fought against both of his parents in the Sin War, the subversive cold war that Heaven and Hell fought over Sanctuary. Throughout time, the Nephalem would slowly have their power dilute as they reproduced, eventually becoming the comparatively-puny Human race. This lineage gifts the Nephalem with incredible power, so much so that the weakest Nephalem is still more powerful than the vast majority of the races that spawned them. Rathma is a first-generation Nephalem, a race created through the mating of demons and angels.

So, if this is true (which it certainly seems to be), what does this mean? Consider this a brief lore check on who the legendary Rathma is, and why his appearance is important to the story – as well as incredibly confusing.

Recently, it seems to have been confirmed that the Pale Summoner in the Diablo IV cinematic trailer is actually Rathma, son of Lilith.
