Lost Valley Redoubt has the wall which has the word of power on it outside. There are Hagraven that hang around the place together with some forsworn who are doing some kind of ritaul with them. It is fairly easy to kill all the people there, just be careful of the Hagraven because they are fairly powerful magicians. You can find Lost Valley Redoubt here:
If you approach this location from the side you don’t have to deal with the forsworn at the bottom of the area. They aren’t difficult to deal with, but it certainly would cut a whole lot of time from this quest. Also the Hagraven and the forsworn don’t expect you to come from there so you get to catch them off guard.
Ironbind Barrow is supposedly full of treasure as you find two people outside of it wanting to explore. I killed them so that they wouldn’t get in my way, but I suppose they would be a nice help if you talk to them and get them to follow you. You can find Ironbind Barrow here:
Throughout Ironbind Barrow there are several trap doors. I didn’t try out whether or not they would open, but it is better to stay away from them if you want to avoid wasting time walking around to get back to the top of the trap door or want to avoid dying.
Close to the end of this dungeon there is a helmet on the top of a pressure plat. It is on an elevated platform as you can see in the image below:
Once you take the helmet off the pressure plate spikes shoot up all around the stand. Quickly take a few steps back to avoid the damage. This action will also open the gate in front of you.
In this dungeon you will find the word of power “Spirit” from the shout “Become Ethernal”. This shout is very useful if you are faced with a high cliff that you need to travel down. It is also useful if you are in a situation were you are almost dead but you are about to kill an enemy and want to avoid using a potion. Simply use this shout and become invincible for a few seconds.
