Pear Yne

“Night, forever. But within it, a city, shadowy and only real in certain ways.
The entity cowered in its alley, where the mist was rising. This could not have happened!
Yet it had. The streets had filled with… things. Animals! Birds! Changing shape! Screaming and yelling! And, above it all, higher than the rooftops, a lamb rocking back and forth in great slow motions, thundering over the cobbles…
And then bars had come down, slamming down, and the entity had been thrown back.
But it had been so close! It had saved the creature, it was getting through, it was beginning to have control… and now this…
In the darkness of the inner city, above the rustle of the never-ending rain, it heard the sound of boots approaching.
A shape appeared in the mist.
It drew nearer.
Water cascaded off a metal helmet and an oiled leather cloak as the figure stopped and, entirely unconcerned, cupped its had in front of its face and lit a cigar.
Then the match was dropped on the cobbles, where it hissed out, and the figure said: “What are you?”
The entity stirred, like an old fish in a deep pool. It was too tired to flee.
“I am the Summoning Dark.” It was not, in fact, a sound, but had it been, it would have been a hiss. “Who are you?”
“I am the Watchman.”
“They would have killed his family!” The darkness lunged, and met resistance. “Think of the deaths they have caused! Who are you to stop me?”
“He created me. Quis custodiet ipsos custodes? Who watches the watchmen? Me. I watch him. Always. You will not force him to murder for you.”
“What kind of human creates his own policeman?”
“One who fears the dark.”
“And so he should,” said the entity, with satisfaction.
“Indeed. But I think you misunderstand. I am not here to keep the darkness out. I am here to keep it in.” There was a clink of metal as the shadowy watchman lifted a dark lantern and opened its little door. Orange light cut through the blackness. “Call me… the Guarding Dark. Imagine how strong I must be.”
The Summoning Dark backed desperately into the alley, but the light followed it, burning it.
“And now,” said the watchman, “get out of town.”

“All right," said Susan. "I'm not stupid. You're saying humans need... fantasies to make life bearable."

REALLY? AS IF IT WAS SOME KIND OF PINK PILL? NO. HUMANS NEED FANTASY TO BE HUMAN. TO BE THE PLACE WHERE THE FALLING ANGEL MEETS THE RISING APE.

"Tooth fairies? Hogfathers? Little—"

YES. AS PRACTICE. YOU HAVE TO START OUT LEARNING TO BELIEVE THE LITTLE LIES.

"So we can believe the big ones?"

YES. JUSTICE. MERCY. DUTY. THAT SORT OF THING.

"They're not the same at all!"

YOU THINK SO? THEN TAKE THE UNIVERSE AND GRIND IT DOWN TO THE FINEST POWDER AND SIEVE IT THROUGH THE FINEST SIEVE AND THEN SHOW ME ONE ATOM OF JUSTICE, ONE MOLECULE OF MERCY. AND YET—Death waved a hand. AND YET YOU ACT AS IF THERE IS SOME IDEAL ORDER IN THE WORLD, AS IF THERE IS SOME...SOME RIGHTNESS IN THE UNIVERSE BY WHICH IT MAY BE JUDGED.

"Yes, but people have got to believe that, or what's the point—"

MY POINT EXACTLY.”
