"Deep into that darkness peering, long I stood there, wondering, fearing, doubting, dreaming dreams no mortal ever dared to dream before." Edgar Allan Poe

“Everyone is a moon, and has a dark side which he never shows to anybody.” Mark Twain

“Stars, hide your fires; Let not light see my black and deep desires.” William Shakespeare, Macbeth

“It cannot be seen, cannot be felt,
Cannot be heard, cannot be smelt,
It lies behind stars and under hills,
And empty holes it fills,
It comes first and follows after,
Ends life, kills laughter.” J. R. R. Tolkien, The Hobbit

“This fall I think you're riding for—it's a special kind of fall, a horrible kind. The man falling isn't permitted to feel or hear himself hit bottom. He just keeps falling and falling. The whole arrangement's designed for men who, at some time or other in their lives, were looking for something their own environment couldn't supply them with. Or they thought their own environment couldn't supply them with. So they gave up looking. They gave it up before they ever really even got started.” J. D. Salinger, The Catcher in the Rye

“There is darkness inside all of us, though mine is more dangerous than most. Still, we all have it—that part of our soul that is irreparably damaged by the very trials and tribulations of life. We are what we are because of it, or perhaps in spite of it. Some use
it as a shield to hide behind, others as an excuse to do unconscionable things. But, truly, the darkness is simply a piece of the whole, neither good nor evil unless you make it so. It
took a witch, a war, and a voodoo queen to teach me that.” Jenna Maclaine, Bound by Sin
