"Troll" is such a harsh word.  Skybuck is more like a "flutterby", a
creature that flits from one hare-brained scheme to another without spending
the effort needed to acquire any significant expertise in anything.  It
would rather spend its time trying to manipulate others into doing its work
so it can later claim the credit.  Of course, if the schemes don't pan out,
it's always someone else's fault.  It's a tough life, but somebody's got to
do it.
