=Act Two Dialogues=
Tyrael appears at the very end of the act, after a player has defeated Duriel., and gives the following message:
<blockquote>''I thank you, mortal, for my freedom. But I did expect you earlier. I am the Archangel Tyrael. I came here to prevent Diablo from freeing his brother, Baal. But I have failed. Now, Terror and Destruction roam free throughout your world. Even now, they head towards the Eastern capital of Kurast - to the very heart of the Zakarum Temple. There they hope to find their eldest brother, Mephisto, the Lord of Hatred who was imprisoned there ages ago. If the three Prime Evils unite, they will be invincible. Though it is unclear as to what their aims are, it is certain that they must be stopped at all costs. I am broken and the energies that tie me to this world are diminishing rapidly. You must take up this quest and prevent the Three Brothers from reuniting. You must cross the sea and search for Diablo and Baal in Kurast. Now hurry, mortal… Time is running out for all of us! ''</blockquote>
