Dream Walker
From Sword of Truth Wiki
A Dream Walker was a weapon created during the Great War. They died out at that time, however more recently the ability of a Dream walker awoke in the form of Emperor Jagang.
Dream walkers have the ability to slip in between the cracks of a persons mind and wedge themselves there. At first they can only appear in a persons dreams, but as the Dream walker becomes more powerful, they are able to enter a persons mind at any time. If a Dream walker wishes it, a person can be made to do anything against their will. No moment that person has ever experienced is out of bounds to a Dream walker.
Most people are in fact protected against a Dream walker as it takes a great effort for them to take over the mind of a person who is not gifted. However gifted people are extremely vulnerable to a Dream walker and this is partly why they were such a devastating weapon during the great war.
At first, there was no protection against a Dream walker and the wizards of the New World searched desperately for some way to protect themselves. It wasn't until the Lord Rahl Alric Rahl created a bond to his people that a form of protection was available. The people's bond to the Lord Rahl protected them from a Dream walker.
This bond carried on down the centuries and is the reason that the people fighting for the cause of Richard Rahl are immune to Emperor Jagang's powers as a Dream walker.
A Dream walkers eyes turn an opaque black once they have reached the height of their power.
