Black Soulstone

Lore & Background

The history of the Black Soulstone is rooted in tragedy and betrayal. Originally, the Soulstone was a tool of the Nephalem, designed by Inarius to trap Diablo's soul after his first defeat. However, over centuries, the stone's power waned or was repurposed until it fell into the hands of those who sought to exploit its potential for ultimate domination. The transformation into the 'Black' Soulstone occurred when the artifact was infused with dark energies, allowing it to hold not just one demon, but the combined souls of all seven Prime Evils: Diablo, Mephisto, Baal, Azmodan, Andariel, Belial, and Duriel. However, the plan backfired when Diablo, realizing the stone's potential, manipulated events to ensure his own rebirth as the Prime Evil of all evils. The stone became a beacon for demonic energy, corrupting everything it touched and serving as the focal point for Malthael's crusade against humanity before its ultimate destruction.

In Their Own Story

The air in the vault was thick with the scent of sulfur and old blood. Inarius stood before the pedestal, his wings folded tight against a body that trembled not from fear, but from anticipation. Before him sat the Black Soulstone, pulsing with a rhythm that matched the beating hearts of seven ancient nightmares trapped within its obsidian depths. 'They think they are free,' he whispered to the silence, his voice echoing off the cold stone walls. He raised his hand, and the shadows seemed to bow. The stone did not just hold them; it fed on their hatred, turning their eternal struggle into a weapon that could shatter the gates of Heaven itself. But as the light within the stone flared, a single, ominous thought crossed his mind: was he the master of this prison, or merely its new warden?
