Extortion is a form of pillage in which the invading army gives the locals an opportunity to buy the troops off and avoid the damage pillaging leaves in its wake. The probability of a fief submitting to extortion depends in the loyalty level of the fief. A fief with a loyalty level of 1 has a 10% chance of refusing, a 9 loyalty level fief has a 90% chance of refusing. If the fief gives in to the extortion demand, it undergoes the same monetary effects of a pillage, but without any loss of life.
