Annah's charm its perhaps what also make her seem "simple" or "uncomplicated", her personality lack the multiple layers of other characters in Torment, but do not see it as a limit or something that make her trivial, for someone to be like her in the Cage its not just a challenge, its a mine of opportunities in narrative.
The Planes, and more particular, Sigil, are places of conflict, where true and lie mingle together in a web so thick than no one can really see what really is happening, every faction have an agenda, every blood have a purpose, even the lowest berk can dream, what if someone is lost and have those things not?, what if a thief no longer craves for jink?, what if the tie that bond friends together broke, leaving only remembrances?
Answers for those questions are what I will seek among your lines, you call it redemption, I will call it surviving, for you a tribulation, for me a good reading to take to bed, for us a chapter among many, for Annah a breath of life on her Torment.
PS gee, after writing this things I realize why its good to take breaks from roleplaying
