:blink: really? I always assumed that option was being from the Thieves Guild, since the guard always said something along the lines of "be quiet" or "I could lose my job over this" and it just said "Guild", so I assumed that meant the Thieves guild. Why would being part of the College give you the option to bribe guards?
You can say that you are with the College, not the Guild

But it's pretty obvious: How could that fact bribe the Guards that you are in the Thieves Guild? They'll be glad to put every thief in the jail.... you would just tell them to do so as you are a thief...
But if you are in the College of Mages, then you might persuade the guard that you are an important mage and that he might let you go once..
