Baal
Enough of your idle speculation, Mephisto! I breached the fortress and saw it firsthand. The Worldstone is gone! The angels I killed knew nothing about it. But since you are so perceptive, maybe you remember who else has been missing: Lilith. We must find her, rip her limb from limb, take the Worldstone back!
Mephisto
Cursed am I to lead an army of the blind. They do not perceive that the angels are fleeing this realm, and the ones they find are merely trapped or lost. A great change is upon us. Withdraw from the fields, my brothers. Some battles can only be won with words.
Diablo
You are all deceived, my brothers. A new age has already begun. Can you not sense them? Ugly creatures, born in shadow, they feel terror, hatred, and the desire to destroy. Yes... but they are not ours yet. But they will open their world to us very soon. An invitation we cannot refuse.
