Acronym for the Faerie Armed Forces Institute.
FAFI is an organization with a number of branches in the Mephitist Empire, and a few in allied states. Its stated purpose is to bring comforts to the enlisted furs of the Imperial & Royal Army. Most squaddies, however, take the view that the purpose of a FAFI is to speed up the process of Embracing Fuma. In particular, the quality of the tea served at FAFI canteens is the subject of much mirth among the soldiers, a few of the more educated ones taking the position that the beverage is intended to be a universal solvent.
