Fascinating race, the Weeping Angels.
The only psychopaths in the universe to kill you nicely.
No mess, no fuss, they just zap you into the past and let you live to death.
The rest of your life used up and blown away in the blink of an eye.
You die in the past, and in the present they consume the energy of all the days you might have had, all your stolen moments.
They're creatures of the abstract.
They live off potential energy.
Don't blink. Blink and you're dead.
They are fast. Faster than you can believe.
Don't turn your back. Don't look away. And don't blink.
Good Luck.
