In my tortured ears there sounds unceasingly a nightmare whirring and flapping, and a faint, distant baying as of some gigantic hound. It is not dream—it is not, I fear, even madness—for too much has already happened to give me these merciful doubts. St. John is a mangled corpse; I alone know why, and such is my knowledge that I am about to blow out my brains for fear I shall be mangled in the same way. Down unlit and illimitable corridors of eldritch phantasy sweeps the black, shapeless Nemesis that drives me to self-annihilation.–HP Lovecraft
