Tyrael
Congratulations, hero!

Surely, even Diablo, himself, sensed the fury unleashed when you smashed his Brother’s Soulstone.

But beware, the Lord of Terror is not to be underestimated. He single-handedly destroyed the town of Tristam and corrupted the last noble hero who tried to stop him.

This time, you must defeat him for good. Only by destroying the Soulstone which he carries will his spirit be banished forever.

Good luck! Though this be our darkest hour, it may yet be your greatest moment.

Find Diablo in his Sanctuary.

When reaching the Sanctuary of Diablo, an angel stands at the entrance awaiting you, to warn you of what lies ahead.

Hadriel
Proceed, hero, into Terror’s lair.

Know that Diablo’s innermost sanctum is hidden by five seals.

Only by opening each of these seals can you clear your way to the final battle.

*Once opening the five seals, Diablo comes forth at the center of the pentagram. After a long fight, Diablo is defeated.

QUEST COMPLETED

Deckard Cain
I knew there was great potential in you, my friend. You’ve done a fantastic job.

Though my ancestors often struggled against the Three Evils and their minions, I’ve always lived a shut in, scholarly life. I’m glad that my wisdom aided you.

Now, I wish to leave this place. Though Heaven’s Gate are a marvel to behold, I hope I won’t have to see them again for many, many years.

Please talk to Tyrael about leaving this place now!

Tyrael
Praise be to the Light! You have accomplished the impossible!

Diablo and Mephisto have been banished back into the Black Abyss that spawned them, and the corrupted Soulstones are no more.

However, while you were fighting here, Baal remained behind in the mortal realm, building an army of hellish minions. Now, Baal’s army is searching for the Worldstone, the ancient source of all the Soulstones and their power, while leaving behind a wake of destruction. They have forged deeply into the Barbarian homelands, heading directly for the summit of Mount Arreat!

Baal knows, mortal hero! hat is the very site of the blessed Worldstone!

Now, enter the portal I have opened for you. It will take you to the Barbarian city of Harrogath, the last bastion of Order on the slopes of Arreat.
