Power is the crushing sensation delivered from somewhere vaguely Above.
It is obtuse; inscrutable.
Ever-shifting and mercurial.
Confounding.
Contradicting.
Nakedly self-interested.
Confident. Conscienceless. 
Faceless. Meaningless.
A black hole sucking everything in.
A black boot in every face.
A blackness.
A contradiction; a cognitive dissonance.
The bitter taste on one's tongue.
The gnawing fear.
Capriciousness.
Corruption.
Hypocrisy.
Paranoia.
Bombastic grasping.
A slap in the face.
An endless arms race.
A shallow grave.
A cold stare.
A trap.
