Mwehhh, for starters, Sword of Truth > Wheel of Time.
Juuuust saying xD
**Nobody get's away with the word wheel of time on the forums, I am stalking you!**
Mehh, I read all 3, I think that Galbatorix and
his dragon get killed. But the Dragon might stop Galbatorix from killing Eragon. My guess is Murthag does not kill Galbatorix or Eragon, and get's killed. But he will be friendly again with Eragon in his last minutes so Eragon can go all emo on us.
Eragon's brother will live, his story line is to promising to let him die. Arya might die, actually. Eragon won't get Arya I think
And if he does, Arya will die for sure because they are to different to have a "happily ever after".
That would be my opinion, eat it xD
