We work in the dark.We do what we can to battle the evil that would otherwise destroy us. But if a man's character is his fate,  this fight is not a choice, but a calling. Yet, sometimes the weight of this burden causes us to falter, reaching the fragile fortress of our mind, allowing the monsters without to turn within. And we are left alone, staring into the abyss... into the laughing face of madness.

The Raven

Once upon a midnight dreary, while I pondered, weak and weary,
Over many a quaint and curious volume of forgotten lore,
While I nodded, nearly napping, suddenly there came a tapping,
As of some one gently rapping, rapping at my chamber door.
"'Tis some visitor," I muttered, "tapping at my chamber door —
Only this, and nothing more."

Edgar Allan Poe
