One night, you see something too big to be a flying insect.  It flashes by your window; something pale.  It zipped by, but you swear beheld humanlike hair.

Curious, you walk out into your backyard, drawn by the sound of movement close to a log.  You creep close, wondering what animal...  

Eyes peer at you from inside the log.  They are humanlike and intelligent.  The log’s size is too small to even hold a child.
