Some people in Gotham City know a nursery rhyme, it tells about the mysterious Court of Owls: Beware the Court of Owls, that watches all the time, Ruling Gotham from a shadowed perch, behind granite and lime.
They watch you at your hearth, they watch you in your bed.
Speak not a whispered word about them, or they'll send the Talon for your head. But every legend has a true part, doesn't it?
