Unlike your last visit to this realm, you'll actually have to do some work here. When you gain control of your character, move forward to the small structure in front of you called a Scrye and activate it. This will lower a bridge in front of you that you can use to jump into the hallway that is swinging around in front of you. Be careful to time your jump correctly because if you land in the goo, you'll start to lose a lot of health.
Get into the hallway and go to the other end. When you get there, wait for the hallway to swing all the way to the right side and hop off. On this platform will be another Scrye. Activate that and wait for the hallway to come back. You should now be able to reach the platform when the hallway reaches the center position. Hop onto the bridge and move onto the platform proper where another book is sitting. Read this book to go to Chapter 2.
Chapter 2
You'll be dropped in a long tube. Walk to the end and activate the Scrye there. This will unfold the bridges that make up this hall and you'll be confronted by three Seekers. Keep moving around so that their projectiles don't hit you and then take them out. When they are dead, look for a Scrye under a blue orb on the wall. Activate that and another doorway will open. Go through this doorway and start reading Chapter 3
Chapter 3
This area consists of a bunch of platforms connected by bridges. Go forward two platforms and when you do, you'll be attacked by Seekers again. The first one will be on a platform to your left and the second one will appear at the top of the stairs ahead of you. When you've killed them, head up the stairs to the very top.
You'll come to another area with platforms over more of that goo that you saw previously. There will be another large swinging hallway here. Just wait for it to come back to you and hop on. Follow the hallway to the end and activate the Scrye to open the door along the way. Inside, you'll bump into a Seeker or two so be on your guard.
At the end, you'll see the hallway swinging around again. Wait for it to swing around to a spot where a bridge is lowering for you. You'll find a lurker waiting for you on this platform. Kill him and you'll be in another moving hallway. This will bring you to a platform with a Scrye on it and a gate. The Scrye will open the gate for you and then you can enter a set of book-caves filled with Seekers. You can likely run right past them if you like or kill them if you want. At the end will be Chapter 4.
Chapter 4
Chapter 4 will start you well above the previous area. You will see a bridge folded down in front of you. If you activate the Scrye just to the right of this bridge it will open up and allow you to cross. The large orb in front of you will unfold and you will find a large book on a pedestal in the center. Open the book to read it and you meet Hermaeus Mora. Talk to him and he will grant you the second word of power that you need. When you are down talking, the book in front of you will start to glow.
Above the book will be three orbs. Each orb has the potential to modify one of your shouts. You can return here by reading this book again to change which one you've selected but you can only select one at a time. Decide which modification you would like and then read the book again to return to Nchardak.
The Secrets of the Skaal
Leave Nchardak but be ready for the dragon that may attack you as you exit. When you are free to do so, return to the Skaal village and talk to Storn. When you talk to him, he'll seem pretty convinced that giving in to Herma Mora is the correct thing to do. You MAY have to finish the quest "Cleansing the Stones" before he feels safe in proceeding however.
After your talk, you'll hand him the book that you were using and he will contact Herma Mora. After he does so, you'll be able to learn the final word of power for the Bend Will shout.
