    What the player is doing to get an encounter, such as surfing or walking
    through tall grass, is called terrain.  Each terrain has its own set of
    encounter slots.

    Within a terrain, slots are defined primarily by rarity.  Each slot can
    also be affected by world conditions; for example, the 20% slot for walking
    in tall grass is affected by whether a swarm is in effect in that area.
    "Is there a swarm?" is a condition; "there is a swarm" and "there is not a
    swarm" are the possible values of this condition.

    A slot (20% walking in grass) and any appropriate world conditions (no
    swarm) are thus enough to define a specific encounter.

    Well, okay, almost: each slot actually appears twice.
