After rescuing Deckard Cain inside the Cathedral, he and the player use the waypoint to rendezvous at New Tristram, in front of The Slaughtered Calf Inn.
There Cain talks about the Texts of the End Days from the tomes of Zakarum. It clearly mentions the Lord of Lies — which for those who missed it is one of the seven Great Evils: Belial, the Lord of Lies. Ohh, you don’t know who Belial is? No, it’s not a new character. Check out the story of The Dark Exile — from the Diablo 1 (1996) manual.
- Duriel, the Lord of Pain
- Andariel, the Maiden of Anguish
- Belial, the Lord of Lies
- Azmodan, the Lord of Sin
- Mephisto, the Lord of Hatred
- Baal, the Lord of Destruction
- Diablo, the Lord of Terror
Of these seven evils, we have already faced five –except for Belial and Azmodan. Check out the dialogue straight from Diablo III closed beta:
Deckard Cain: The Skeleton King was once our beloved lord, Leoric. He was driven mad by Diablo’s evil. He lost both of his sons — and his very soul — before he was finally defeated. Now it seems he’s risen to plague this land once again.
Monk: Nonetheless, the Skeleton King bars my path to the fallen star.
Deckard Cain: The key to defeating him lies in his old crown. Seek out our blacksmith Haedrig; he knows of its whereabouts.
Leah, you should not dismiss the signs so lightly. Do you not believe the evidence of your own eyes?
Leah: Horros have visited Tristram before and it endured.
Deckard Cain: But what of the texts? The Zakarum tomes warn of a falling star. The Horadric Scrolls spoke of the dead rising and the Lord of Lies. The Prophecy of the End Days says that at the end of all things, the first sign shall appear in the Heavens!
Leah: Yes, you’ve been telling me about the texts since I was eight years old, Uncle. I just don’t think we should read too much into them.
This interview from Blizzcon 2009 got linked to me, final paragraph on page 3 – Belial will be in Act 2:

Jay Wilson: “Act two’s a little bit more of an intrigue and deception-focused story, because Belial is in there. Act three, there’s a lot more.”
I believe act 4 will be in heaven, and I believe Diablo is now THE prime evil (combining diablo + baal + mephisto into one big bad ass monster)
I also believe belial and azmodan will also be in the game (act 2 and 3 maybe?)
AND I also believe Leah is not showing us everything… maybe she’s already one of those prime evils, or she will become one, or she will be used on some dark magic or something…
