This was predicted many years ago...
"The soulstone burns with hellfire, as an eerie red glow blurs your vision. Fresh blood flows into your eyes, and you begin to hear the tormented whispers of the damned.
You have done what you knew must be done. The essence of Diablo is contained... for now.
You pray that you have become strong enough to contain the demon, and keep him at bay.
Although you have been fortified by your quest, you can still feel him, clawing his way up from the dark recesses of your soul.
Fighting to retain control, your thoughts turn to the ancient mystic lands of the Far
East.
Perhaps there, beyond the desolate wastes of Aranoch, you will find an answer. Or perhaps... salvation!"
