This tale is older then the legend of Nightmare Moon, older than the legend of Discord, even older than Equestria itself.
Over ten thousand years before the return of Nightmare Moon an evil was sealed away and forgotten by all except those that guard its prison.
This tale is of a young filly who's family has recently suffered a terrible loss. And an entity that does not belong to this world. It is a tale of Necromancers and those who seek to destroy them. It is a tale of tragedy.

Many have heard the tales of the creature known as the Bogey Pony. But none alive know of where it came from. Take a glimpse into the past, and see the origins of the one known as Glam, the Bogey Pony.

((The story's main character is based on the character from this blog http://glam-the-shadow-pony.tumblr.com/ ))
