Merchant of Menace
Any character with an Intelligence of 10 or more, who has lived in Sterich for a number of years knows the information linked below, regardless of whether they have any ranks in the associated knowledge skill (i.e. it is common knowledge).
If a character has less then an Intelligence of 10 then they would have to make an Intelligence check of DC 10 to make use of the information below however it is highly unlikely that this scenario will be relevant in the game so I am making the information available to all players.
