Pathfinder Orson Scott Card Most Interesting Talents Rigg is not a normal kid. Neither is Umbo or Param. Rigg is the pathfinder, having the natural ability to see where any living creature existed. Umbo is the time manager, slowing down time around a person, object, or himself. Param is the time slicer, cutting down the time in which she exists, effectively turning her invisible to the naked eye. Those are some pretty interesting talents for some otherwise normal kids.
