Chamberlain

The history buffs among you may remember the story of Joshua Chamberlain.  Others may have had to pull out their devices to access google.  But it becomes clear, very quickly, that the 'riddle' this wisp gave was perhaps the most literal.

Chamberlain was a General who fought with his men at the battle of Five Forks - April of 1865 - despite having been severely injured in June of 1864.   He died 50 years after his wound, from complications OF his wound.

It fits the riddle perfectly.

And of course, you remember where he was last seen.  Your intelligence report shows that he has been seen haunting the tracks of the Roller Coaster, and you had caught a glimmer of a ghost there earlier.

So to the Roller Coaster you go again.  The weight of being watched has lifted, a little... but the air still feels heavy... it still feels different from how the air usually feels in this little slice of purgatory.  

The riddle said to 'free the knife', and so you assume that you must remove some sort of spectral blade from the ghost of this General in order to break the hold of whatever has taken the Park... or at least, some of you think this.

But these thoughts are interrupted as you hear the most hair-raising scream you have ever heard.  Wendigo cannot compare to the agony that ripples in the air... from above you.

There, on the tallest point of the Coaster Tracks, you see something devouring the ghost you had been meant to free.  Its shadowy maw opens, and bit by bit it shoves chunks of that ghostly essence into its gullet.

Joshua Chamberlain is truly gone before any of you can think to try to take action.  And the thing... sees you.  With a graceful leap it jumps from the tracks, plummeting towards the ground.  Before it would hit, shadowy wings lift, breaking its momentum to allow it to hit the ground on all fours and hiss at your collection of exorcists.

It does not attack you.  It screams at you, and for a moment, you feel the urge to run.  Something primal in you recognizes that this is something that will do more than kill you... you will cease to exist.

But it does not attack.  It twists about, taking great leaps towards the fence... towards the cliff...and then it is gone.

No sooner has someone brought up trying to find the Boogeyman to ask what the hell has been haunting his Park does he show up, his strange waddle and twisted gentlemanly appearance truly disturbing in its gaiety this time.
  He doesn't try to kill you. There is at least that much.
  "Such a pleasure to have such chivalrous 'knights' defending the homestead... let me give you a hint, sweetlings..."

  Come in from the West to steal the dying - to make brother fight brother and bring on the crying.
  Come in from the Night to feast on the bones, so rarely spotted yet so rarely alone...
  Beware little bee for I will be blunt... they rideon the winds of the great Wild Hunt!

He leaves you, his creepy laugh echoing in the wind as he blends with fog and mist.  The Boogeyman controls his home again.
