(NOT IMPLEMENTED!) (Passive) [Familiar] INT
  Possessed By: Some Humans, Grey Elves, Bards, Druids, Mages, Monks, Paladins, Rangers, Rogues, Loremasters, Tattoo Mystics, Twilight Huntsmen, Knowledge priests.
  Effects:  The Knowledge (Theyra) skill has the following uses:
   * Map Memory (Passive, Unimplemented): Characters with this skill will find that there is a radius of the overland map already visible around heavily inhabited or famous areas such as cities, ruins and roads based on their skill rating, illuminating areas they might want to travel through or explore. At low skill ratings, this ia a very tiny radius and only appears around the most significant population centers; at higher levels of skill, it is larger and appears around towns and other smaller population centers. At the highest levels of skill, certain secret locations that cannot be found in other ways might be revealed in this manner.
   * Area Familiarity (Passive, Unimplemented): Travelling through areas that are made familiar with this skill is both quicker and safer than travelling through other areas. The chance of encounters is less, and there is a bonus to Wilderness Lore checks made in the area.
