The Eternal Conflict

At the heart of Diablo 3’s narrative lies the Eternal Conflict, an age-old battle between the High Heavens and the Burning Hells. This cosmic struggle serves as the backdrop for the events that unfold in Sanctuary, the mortal realm caught between these two opposing forces.

The Creation of Sanctuary

Sanctuary was born from an unlikely union between the angel Inarius and the demon Lilith. This hidden world became a refuge for angels and demons weary of the Eternal Conflict, and eventually gave rise to the nephalem – powerful beings who were the ancestors of humanity.

The Sin War and the Worldstone

The discovery of Sanctuary by both Heaven and Hell led to the Sin War, a covert battle for the souls of humanity. This conflict culminated in the creation of the Worldstone, a powerful artifact that suppressed the nephalem’s powers and hid Sanctuary from the cosmic forces.

The Dark Wanderer and the Worldstone’s Destruction

The events of Diablo and Diablo 2 saw the Prime Evils – Diablo, Mephisto, and Baal – attempt to corrupt humanity and conquer Sanctuary. The destruction of the Worldstone at the end of Diablo 2: Lord of Destruction set the stage for the awakening of humanity’s latent nephalem powers.

The Coming of the Fallen Star

Diablo 3 begins with a fallen star crashing into Tristram Cathedral, setting in motion a chain of events that would shake the very foundations of Sanctuary. The player, as a nephalem hero, embarks on a quest to uncover the mystery behind this cataclysmic event.

The Return of the Prime Evil

As the story unfolds, it’s revealed that the fallen star was actually Tyrael, the Archangel of Justice, who chose to become mortal to aid humanity. His fall releases the trapped souls of the Prime Evils, allowing Diablo to be reborn as the Prime Evil, a combination of all seven Evils in one being.

The Reaper of Souls

The expansion, Reaper of Souls, introduces Malthael, the former Archangel of Wisdom turned Angel of Death. Malthael seeks to end the Eternal Conflict by eradicating humanity, whom he sees as demonic abominations due to their mixed angelic and demonic heritage.
