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

do آپ mean champion of the arena?

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

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

I think because the politics of the monarchy,the kings یا Septims are at the سب, سب سے اوپر so they have the
ability to use the whole tower floor 1-5,Ocato 1-3,you 1-2.

because آپ are just a fighter not a guard

I dont know probably its A glitch یا something xD
