Yes, it was supposed to have several areas (there are some incomplete AREs in the 2630 range or so that were work-in-progress for this stuff). There's no chance of this sequence ever being restored.
Basically, you'd face a series of "tests" in a number of areas, acting based upon your alignment (very similar to the Abyss tests in SoA). So you'd have a poisoned man that you could save from gnolls; a wizard who needs a powerful potion to save himself (but that you could decide to drink instead); an evil paladin who will attempt to get your aid in destroying a friendly ogre; etc. Stuff like that, and all the while, there'd be a disembodied voice trying to get you to give in to your evil nature (with a number of comments before and after each "test"). It's way too involved to be restored, and really very little beyond what can be inferred from the remaining strings is actually in the game.
