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 fell him, clawing his way up from the dark recesses of your soul.
Fighting to retain control, your thoughts turn towards the ancient mystic lands of the Far East. Perhaps there, beyond the desolate waste of Aranoch you will find an answer, or perhaps, salvation.
