The
Worldstone Chamber is the final level of Act 5 (excluding the
Pandemonium Event levels) in which you face the game's final boss,
Baal.
Tyrael reports to you that it is too late after defeating
Baal, and the room begins to shake as the Worldstone begins to disintegrate. After proceeding through the dialogue, you are then presented with the final cinematic of the game and begin a new game in the next difficulty.
