Ive read the three previous books and cant wait to get the 4th one i posted a theory somewhere on another site about the rock of kuthain and vos but i can remember it

i will try to find it and post it here =D
Found my theory that i posted on another site a while ago:
I've recently been reading ROK posts and come up with my own crazy theory
In book 4 there will be another rider which will most likely be on the vardens SIDE meaning Eragon and Saphira will most likely steal it, possibly with the help of Ayra though they wouldnt dare to walk into uru baen on open ground this is where the elven outpost where Tenga lives comes into play. So far we know Tenga must be a powerful magician and or a descendant of the grey folk if not a grek folk from him casting a spell without the ancient language. Tenga lives in a elven outpost which undoubtoudly must of had secret access to the elven capital illreia/uru baen.
1. it was most likely an outpost in the elven war with dragons, dragons rule the air and thefore could deal large damage to a elf running across toward their city overground so? They used underground tunnel to avoid dragons and other dangers and safely traverse the distance to send a warning illreia effectivly.
My theory is based on the fact that i think RoK is underneath illreia as elves built cities around places of magical importance.
That RoK is pre elf and is to do with or created by the grey folk as they were one of the orignal species of the land.
Elves discovered RoK but kept it a secret higher than HoH and made it a fleeting memory in elfs minds
certain wards have been placed around RoK so that unless your true name is pure and intentions are good you cannot enter the tunnels maybe?
I think after eragon saphira and ayra get the green egg galbotrix will notice the intruders, Eragon will want ayra to take the green egg and Saphira to fly back to the varden with haste while staying behind to stall for time he will go back to the tunnels and find out that Galbortrix and his men cannot enter Eragon will see the seven words Brom said to him somewhere in the tunnels and enter or inspect that door/wall revealing RoK
I remember reading on shurtgal ,i think, that Eragon will be captured but not by Galbortrix i think he will be captured by tenga for seeing RoK but will remain rather close to the rock tenga will want to find out Eragons true name to find out how he managed to get into the tunnels and if he is a threat and if he is to break him using his true name.When tenga finds eragons true name he will tell it to eragon who may go into shock but eventually because his true name isnt evil recover and speak it to the RoK i think the RoK like someone else said that when eragon activates the RoK he will be in touch with everything in alagaesia being able to draw energy form wildlife leagues away in a sense be able to do the thing that oromis trained him to do in the glade(when Eragon kept focusing on ants but learned to open his mind to other beings around him) but with the whole of Alagaesia allowing him to relinquish Galbotorix's control of the eldunari and free murtagrh from his fealty but i think this will also be the reason he leaves alagaesia because of being able to feel everyones pain in Alagaesia.
I think the VoS contains nothing(or nothing that Eragon wants to release i think the vault of souls was used to seal away the terrors that were unleashed through magical incidents before magic was sealed to the AL) but rather will become a vault to something Eragon wants stored away like Vrael i dont think earagon will be able to strike the final blow to galby he has proved already with Sloan that he is not a executioner and as Brom said his fight will be more of a mental one than physical or magical so when he gains dominiance over Galbotorix it will stay that way for a good period of time meaning if he killed him it would be in cold blood not exaclty Eragons style is it? So while he has dominance over him he will seek to lock Galbotorix in the Vos trapping him in an eternal prison to ponder his wrongs also i think eragon will tell Galbotorix his true name before putting him into VoS and maybe like sloan giving him a chance to reeedem himself through his true name changing for good.
Sorry for the long read and lack of punctuation i hope no one attempts to read this aloud ><
Also something else thats off topic is the whole soilders lost in the spine i think its Vrael dragon since when Vrael was killed at utgard mountain he was kicked in the fork of his legs meaning he was fighting on his own two feet not on his dragon meaning he could of sent his dragon away to hide in the spine unless of course they both just decided to dismount their dragons like Mutargh and Eragon did on the Burning Plains.
Hope you enjoy my crazy theory again sorry for the long read
