Why can't toi go into the imperial gaurd places even though toi are know as the Champion and still can't be in guard bartracks and stuff like that?

do toi mean champion of the arena?

Because thats how it is no matter what toi do they wont allow it but on some occasions the guards don't ask me to leave at all!!!

If toi mean the Imperial Palace and the other areas like Ocato's room toi have to do the Theives Guild quest but if toi mean the reagular Barracks then idk but toi can illigaly ^_^

I think because the politics of the monarchy,the kings ou Septims are at the haut, retour au début so they have the
ability to use the whole tower floor 1-5,Ocato 1-3,you 1-2.

because toi are just a fighter not a guard

I dont know probably its A glitch ou something xD
