   // You can create multiple effect sets for different character types.

   // Actions, locations, and things can affect desires.
   // For example, drinking in same room as water dish reduces thirst.
   // "action", "thing", and "location" are cumulative requirements,
   // so [action "drink" thing "water dish" reduces thirst] will reduce
   // a character's thirst by some random amount only if they are currently
   // doing "drink" and they are next to "water dish".  Thus, their
   // thirst will not be reduced if they are next to "water dish" but
   // doing something else.  An effect of [thing "heater" reduces cold]
   // would reduce cold regardless of their action, so long as they were
   // next to a heater.

   // desires, but it is really the character's effect list that does that.
   // You might make the character believe that walking to the kitchen
   // will alleviate thirst, but in truth you only want to get them closer

   // <action verb>           (what character can do to try to satisfy desire)
   //   [<to "location">]     (taking action moves character to this location)
   //   [<from "location">]   (requires character be at this location)
   //   [<thing "thing">]     (requires this thing be present)
   // <reduces desire>        (character only believes this to be true)
