In Eldest, when Eragon was leaving Helgrid (when he finished to kill the Ra'zac) he found one person who was looking for something. My theory is: That person was looking for the real name of the Ancient Language.

In Eragon, Brom said that AL's name is a thing that nobody knows. He said that this is a name that could give a lot of power to the person who discovered that name.

What do you think about?
Could my theory be probable?
And if it is, could it help Eragon or Galby?
What do you think about the person that I mentioned? (I can't remember his/her name..)
