After successfully outsmarting the planetar, we are ported out of the pocket dimension, and into a fragment of the tower, which Nezbit thinks is another pocket dimension.

Follow up:

the tower hangs lithely in space, fragments everywhere.  We begin searching around and encounter a harpy statue that animates.  It was weakened, and we take it down, but psycho takes a beating and rages on hack.  I sleep him into submission

We find a Githzerai, apparently a friend of Nesbit's.  Weird ass critter that are warrior monks with psyonic attacks.  He was hired by dantessa naroo to find Weijass, or what was left of her.  We learn how he got this far -- how he passed the first dream.  He explains how the others were killed and how he was preparing his soul to exit this realm.

We talk to him about his techniques, but I personally find them to be incomprehensible and futile.  This fool will die here on this plane.  He seems to think we will too.

We rest for the night and re-memorize

We use 2 pelor peps to get to the next level.

The fog grows warmer.  We faintly hear screams of torment.  The light starts to shine in all around us.  A male voice says "we have penetrated past the first of these vile creatures  Be ready to flee once we have rescued her from here".  We find ourselves standing in a cavern, the sides of which pulse as if alive.  The floor is uneven and malleable.  There are mounds of people prostrating themselves in undulating piles, and near the center of the room on a raised platform lounges a dark and horrifically beautiful creature with wings.

A planetar next to us unfurls his wings.  Hold Brothers --- We are here to resuce you!  Step forth into the light sister that we may rescue from this charnal pit of Granaat.. You no longer have to suffer his torments.

She uncurls and stands.  "But what if I now do not wish to leave, Brother.  Perhaps it is you who has come to visit me for an extended period.  Grazaat left some time ago."

Dude looks at us for an explanation.  She spreads her hand out and tentacles erupt from the storm.Rubbery flesh-like tentacles wind about all our bodies, including the Solar.  She steps down and heads towards out group.  She looks at the solar and says "You are here to service me now."  He seems to switch to complete obedience and undying love.   She trails her hand across his face.  He is entralled.  She attempts to seduce Torch, but fails - her hand seared.  Torch sees her as she is - half her body is flayed and burned, bits of bone and tendon sticking out.  I do not fear her look.  She approaches each player in turn, we all rebuff her.  She commands the solar looking Dava to attack us.  The Dava is a formidable challenge, but we prevail and the memory relinquishes.

She was brought to the abyss an disfigured, tortured, and used for Grazatt's pleasures - the force of good reclaimed her at the end of that scene.

We use the keys to step into the next area, and arrive in what is left of the library.  There is a truth area, and the area of falsehoods.   The falsehoods reveal a pattern of falsehoods of the univese as we know it.  From the truths - books - 50 books worth 100 gp ea - detailed accounts of the godlings, collected over the last 500 years by the church of weijass.  We find information that weijass had implmented protections against the summonings of demons.  After the devil attacks, she found that information seekers would find higher resistance.  We learn:  confirmation, names, and outer planar types of all the outer godlings.  With this information we can lookup deific pretender.  We come across a section of books that has to do with devil attacks - i learn of an item that can protect us from the demons - a circlet that will shield my mind and no devils will come and attack me (10,000gp). We discover that the most important books have been moved to her personal bedroom.

So much more information to be learned here.  Why must the plane be disintigrating under my feet?
