The Chelish newspaper of record - though it's not like the other ones are unapproved by the Crown - sometimes contains a weekly advice column by Abrogail Thrune, with a special focus on conduct in Chelish relationships: Dear Abrogail.
Cheliax being what it is, the newspaper doesn't usually bother trying to track down apparently seditious submissions - due to the number of clever individuals who try to fake an ill-advised letter from somebody else, forge their signature, and submit it through the mail system. Anyone who wanted advice on a heretical problem, as the column does sometimes deliver, would just send the letter with a false return address.
Tavern arguments are widespread about whether the Queen really writes this column, just approves the responses, or if it's simply a Crown official somewhere and the real Abrogail hardly ever hears of it. The popular conceit is that the replies are too witty for that to actually be the Queen. More likely it's some public relations office whose current inhabitant gets executed and replaced every four months, for either offending her Infernal Majestrix or for not being witty enough.
Anyone who knows Abrogail personally is pretty sure that it's her.
