Can you identify this Black Plane or Spaceship with black arches for wings? Can anyone help me to ID this incomplete LEGO set?  It looks like a black plane or spaceship to me.
This is not a set,

The Tile 2 x 2 with Gold Crown on Light Bluish Gray Background Pattern  comes from 70404-1: King's Castle

the Brick, Arch 1 x 5 x 4 in Black does not appear in this set so it is probably a part of a MOC
