Countering the Forgery SkillEdit
The rules say that Forgery is opposed by the Forgery skill, presuming that the only way to detect a forgery is to look for techniques in producing the document that a forger might use. But there are other ways: familiarity with the kingdom's paperwork would allow someone to detect a forgery, for example.
Therefore, Profession (bureaucrat) can also directly oppose a Forgery check. Knowledge (local) can also, but at a -10 penalty to the roll.
