  46     Within a given area in a given game, encounters are differentiated by the
  47     "slot" they are in and the state of the game world.
  48
  49     What the player is doing to get an encounter, such as surfing or walking
  50     through tall grass, is called terrain.  Each terrain has its own set of
  51     encounter slots.
  52
  53     Within a terrain, slots are defined primarily by rarity.  Each slot can
  54     also be affected by world conditions; for example, the 20% slot for walking
  55     in tall grass is affected by whether a swarm is in effect in that area.
  56     "Is there a swarm?" is a condition; "there is a swarm" and "there is not a
  57     swarm" are the possible values of this condition.
  58
  59     A slot (20% walking in grass) and any appropriate world conditions (no
  60     swarm) are thus enough to define a specific encounter.
  61
  62     Well, okay, almost: each slot actually appears twice.
