In dark, unexplored depths of Equestria's woods and rivers terrible monsters lurk among the darkness, waiting to be revealed.
In the lonely corners of Equestria's cities and towns, cultists worship unnameble beings and consort with eldritch powers beyond comprehension.
In the forgotten ruins of the past, relics and forbidden tomes from darker times lay ready to drive any who discover them to new depths of horror and madness.
In the void beyond Celestia's Sun and Luna's Moon, ancient, unspeakable horrors prowl the starways, preying upon hapless worlds that came within their grasp and burn with their passing.
It is a comfort to know that tranquility and peace prevails in Equestria thanks to the Magic of Friendship, but what applies INSIDE the ponies' little world bears no relation to what lay OUTSIDE; for Equestria and its little world are no more than a fickle candle-light of order, sitting upon a lonely rock. Beyond it is a hostile and terrifying place, a turbulent, endless ocean of darkness. And at any moment, it would overwhelm all without a thought or care.
Against the gibbering madness and unspeakable evil beyond it there could be no real victory. Hope is a lie. The curious, the wise and the determined are all doomed to madness and death. What better then, to live in ignorance of the vast, horrible reality that lay behind the illusion of peace and harmony?
Princess Luna, "I AM one of the unspeakable incompressible horrors you speak of! It is MY cults that are many and rooted! Be gone pretenders! I AM THE NIGHT! The darkness, the moon and stars, all bend to my will."
