It just occured to me ~ now that Galby is out of his castle, and he is extremely, extremely powerful with all of his heart of hearts, what will he do next? He could probably kill Eragon with one word and then the Varden would lose for sure. Maybe he will go back to his castle. Any ideas?

he isnt neccisarly out of his castle thats just one of nassuada eldest conclusions

Well, he was out of his castle when he killed Oromis and Glaedr, so he will probably stay out of his castle.

I didnt think he was out i thought he just used murtagh as a mouthpeice and did the magic through him kinda like the elven blacksmith did to eragon

Thats what i thought

i don't think galby will ever come out of his castle. i think he is scared of something. possibly he isnt quite as powerfull as he has everyone beleave ,don't get me wrong he is still mega powerfull, i just think his power can be taken more easily than he likes so he stays safe in his castle plus if he left the castle he wouldnt be able to bring all the HOHs with him so he would be less powerfull in the open.

yeah and you have to be toutching it to draw energy from it
so if he leaves Eragon will destrow him with strenth of the sward and magic now that he is a elf and he is stronger at magic and strenth

i think he is scared of losing his second dragon, because he cant take murtagh's if shruikan dies, and the green dragon wont hatch for him. also, he did use murtagh, he never came out of his castle, to kill Oromis, and Glaedr. And, i dont think Eragon could kill him without another rider and alot of skill, because, sadly, galby has alot of eludnari.
